What can I do as a woman after menapause do to improve on my Cholesterol and Triglyceride blood results?

Q. In April 2006 my blood work showed: Cholesterol 167.6; Triglyceride 220.4 and HDL 38.1. I am talking Lipitor during both of these blood tests.
In October 2006 my blook work showed: Cholesterol 211.1; Triglyceride 143.7 and HDL 48.5.
I listed the HDL because I was afraid the Lipitor was effecting my Good Cholestrol count.
I'm looking for someone that can tell me why my cholestrol went up this time and triglycerides went down and what is my next course of action.

A. Eat cabbage, oatmeal, apples, etc. for soluble fiber and of course some type of exercise.

Also, here's some all-natural supplements that are very effective.

OmegaGuard: reduces the risk of heart disease/stroke, lowers triglycerides and cholesterol

Soluble Fiber (e.g. Fiber Plan): prevents fat absorption; reduces stress on heart by minimizing fat accumulation

Lecithin: converts serum cholesterol to good HDL

CoQHeart: Reduces LDL oxidation

Garlic Complex: prevents clotting; dilates small blood vessels; dissolves fatty deposits & thins blood

Hope this is useful and feel free to contact me with questions.

What determines whether a triglyceride is saturated or unsaturated?
Q. Is it the bonds?

A. A trigylceride (fat) is basically a glycerol molecule joined to three fatty acid molecules. The fatty acid molecules are often called "fatty acid chains" or "fatty acid tails".

Triglyceride structure:
http://www.indiana.edu/~oso/Fat/FatImg/triglyceride.jpg

If a triglyceride contains fatty acid tails with only single bonds in their structure, it is said to be saturated (saturated with hydrogens - it contains the maximum no. of C-H bonds).

If a triglyceride contains one or more fatty acid tails which contain at least one double bond in their structure, it is said to be unsaturated.

Here is a pic which shows the difference between saturated and unsaturated fats:
http://www.realfitnessblog.com/wp-content/uploads/2008/11/fat_f2.jpg

As the pic above shows, saturated fats are usually straight, so the molecules can pack together tightly, which is why saturated fats are solids at room temp. The double bonds in the structure of unsaturated fats makes kinks in the chain preventing the neat packing together of these molecules, so most unsaturated fats are liquids at room temp.

What is the function of Triglyceride and Phospholipid?
Q. Also, what are some examples of nucleic acids besides DNA and RNA?

Thanks!

A. Triglycerides and Phospholipids are present in the Plasma Membrane of the cell to make each cell regionally distinct from one another.

High cholesterol, when do you have to start taking medication?

Q. My hubby's reading today was
HDL - 61
LDL - 167
Trigy - 89
Cholesterol ratio - 4.0
Total cholesterol - 246
Fasting glucose - 93
Blood pressure 138/80

Does this look normal or should he be on medication due to the high LDL? At what readings should a person be diagnosed with medication? Appreciate your kind replies.
Thanks so much for your kind reply, Pauline.

A. Its not bad... and definitely not bad enough to take medication. I am not a doctor but I am a natural health nut who has family with high cholesterol and I watch this stuff closely.

Medication is an absolute last resort. What you will usually get is Lipitor and one your on that, its pretty much forever.... its tailored that way.

The best way to lower cholesterol is change your diet.. figure out what foods created it in the first place (chips, mashed potatoes and gravies, red meat, bacon.....its pretty obvious what does unless you just naturally produce cholesterol in your bloodstream) and eliminate them. A good routine is always eat a whole grain breakfast within 30 minutes of waking in the morning (even if you dont eat breakfast, its the most important meal and your cholesterol will lower just by doing that in most cases)as well drink 8 to 16 oz of water, clean fresh water, not tap. Then eat fibre througout the day at least every two hours.. carrots, apples, fibre bar whatever.... drink lots of water (this is the nectar of life, it has been neglected for years but science is realizing its really important to keep cells in your body working properly). There is also another thing you can do... drink an ounce of apple-cider vinegar every morning..... it cleans the arteries.... and get a multi-vitamin that contains B50 and niacin.... these also help keep the arteries clean and feed the heart which is what we worry about with high cholesterol. I know this is long but I just wanted to help... I dont promote taking any pills for quick fix... because its not good for your body to take pills.. then you have to take other pills to offset side effects and the next thing you know you have 20 pills to take every day.. the body isnt designed to filter pills..... which is why I believe people are sick in this day and age.

Good Luck

How is cholesterol calculated and can you have too much good cholesterol?
Q. I went to the doctor and my cholesterol was 246 which isn't so good but my good cholesterol was 65, which she said is great. Is the LDL what's remaining after the good cholesterol is subtracted from the total? Can you have too much HDL?

A. HDL are "high-density lipoproteins" which is fancy doctor talk for cells that are high in protein, low in fat/cholesterol. This is preferred, as this is what "feeds" the body with growth proteins. Proteins power "cell" creation and repair (only). Things like muscle, skin, hair, etc...anything that grows or requires frequent repair benefit from higher counts of HDL. HDL's increase in demand with more activity. Specifically 'cardio' (meaning heart) workouts. You really can't have "too much" HDL's because if the body doesnt need the level of proteins in the blood sugar, it simply release it as it passes through the kidneys. We pee out excess proteins. They do NOT convert to bodyfat like some bodybuilders like to beleive.

LDLs are of course "Low density", meaning low protein high fat. LDL's partially provide energy to "active" muscles. The cells are often "coated" with saturated fats. As these move around the body feeding active muscles, they 'bump along' the artery walls, the leave little "skid marks" so to speak. These marks build up to become plaque, and can cause heart decrease. Reducing LDL's to under 200, (or 150 even better) would be good advice but often requires medication, diet modification, AND more physical activity.

How much cholesterol would be in a ostrich egg?
Q. Actually, you can eat ostrich eggs. Eggs are eggs. Just to let you know.

A. An ostrich egg is supposed to be equal to 2 dozen chicken eggs. That would mean 2520 grams of cholesterol.

What does it mean if my triglyceride is low?

Q. I am a young adult and recently had a blood test taken. My triglyceride level was a low 26, the norm is 35-160. What does this mean and what are the risks of having a low amount? Also, what is the function of triglyceride and how can I raise it?

A. Triglycerides are the form that dietary fat takes in your blood. You do not want to raise your trigylceride level because it can lead to heart disease and other health complications. Its best to keep it low.

Can triglyceride levels in dogs increase from the chewing/eating of rawhide?
Q. I have increased the amount of rawhide chews I give to my Beagle, and coincidentally, her triglycerides soared. Is there any connection between the two? Otherwise, she is fed Nutro Ultra for Seniors dry mixed with a little bit of canned and water for a sauce. She is not fed fats, and has a healthy diet of fruits and veggies for snacks.

A. most raw-hides are deep fried or oven basted with chicken fat as dripping, so are just full of fat. You can get healthier ones if you search, but they cost more. Most people recommend the nylon bones, but I have heard if they are too small the dogs can swallow them whole, then you will need an operation.

I give my dogs a small healthy meaty bone to chew daily, its part of their breakfast calorie, is natural and much lower in fat.

Why is a triglyceride considered hydrophobic when it has a glycerol molecule which is hydrophilic?
Q. also- can everything be categorized as hydrophilic and hydrophobic?

lastly- if the outside of our membranes is hydrophilic wouldn't we dissolve in water?

A. The hydroxyl group of glycerol joins in an ester linkage with the carboxyl group on the lipid leaving a hydrophilic compound.

Not all compounds are one or the other some are amphiphilic with a polar hydrophilic end and a nonpolar lipophilic hydrocarbon end like the phospholipids in cell membranes.

How to induce Low density lipoprotein or bad cholesterol levels on rabbits please?

Q.

A. Estrogens induce low-density lipoprotein receptor activity and decrease intracellular cholesterol in animals hepatoma cell line Hep G2.

A new reagent effective in inhibiting cholesterol synthesis 75% in human fibroblasts derived from patients suffering from the disease familial hypercholestrolemia is mannose-6-phosphate-low density lipoprotein and is effective in tissue culture test systems at 100 μg/ml after a ten-hour exposure. The broad purpose of this invention is to modify the receptor specificity of a protein so that it will enter cells which were previously impermeable and exert new effects or reverse a pathological condition. Toxins may also be modified in this manner producing cell type specific and tumor suppressive reagents which are effective in a dose range of 0.3-3 μg. The object here is to use the reagent to selectively kill one cell type which is exerting a pathological effect without affecting normal cells. Among others to which this invention is applicable are Man6P-low density lipoprotein, Man6P-ricin, Man6P-Modeccin, anti Thy 1.2 monoclonal antibody-ricin and anti Thy 1.1 monoclonal antibody-ricin.

Take care always!

How are low density lipoproteins related to health, diet, and cholesterol?
Q. I need the answer by tonight

A. Good cholesterol is high density lipoproteins (HDL) and bad cholesterol is low density lipoproteins (LDL).

Unsaturated fats (most vegetable fats such as nuts, beans, peas and lentils) will increase your HDL level, decrease your LDL level and also reduce your overall cholesterol.

Saturated fats are mostly LDL.

what is LOW DENSITY LIPOPROTEIN RECEPTOR GENE and what does it do?
Q. i was just wondering what it is.. it doesn't need to be detailed or anything, just a simple english answer

A. I believe that a Low Density Lipoprotein receptor gene is a gene that makes an individual more susceptible to accumulating LDL in their bloodstream. As a side note, LDL is the so called "bad" cholesterol that can stick to fats and cause a blockage in the body.

Do we need both HDL (High-density lipoprotein) and LDL (Low-density lipoprotein)?

Q. If so, then how do vegans exist?

A. The liver and the intestines both form lipoproteins such as HDL, LDL, IDL and VLDL. Levels of each are determined by multiple factors. For example, the fats that are carried by the lipoprotein particles come from food and from fat synthesized by the liver.

Eating foods high in cholesterol actually has little effect of serum cholesterol levels(1). The body has a sensitive feedback mechanism that tightly regulates the production of cholesterol (2). When dietary consumption of cholesterol increases, less is produced by the liver. High levels of insulin increase the synthesis of cholesterol by the liver and also by individual cells in the body.

Fats do have an effect on the levels of HDL, LDL and VLDL. Saturated fats strongly increase HDL and to a lesser estent, LDL. Polyunsaturated fats tend to lower both HDL and LDL. A higher refined carbohydrate intake can strongly increase the serum levels of triglycerides, which can also increase LDL. The liver produces primarily palmitic and palmitoeic acid from carbohydrates. Palmitic acid is also the predominant fatty acid in animal.

Since production of HDL, LDL and triglycerides is mediated by many factors, it is impossible to make many generalizations about the association of dietary fats and carbohydrates and serum cholesterol. Very low carbohydrate diets can result in a more favorable lipid profile than a low fat diet (3). Strict meat eaters can have a fairly low serum choleserol while vegans can have a higher serum cholesterol. People eating a paleolithic diet and a vegan diet can have similarities, in so much that both ways of eating discourage the consumption of vegetable seed oils, refined carbohydrates and favor eating whole foods.

What will I do inorder to know my rabbit's high density lipoprotein (HDL) and LOw density lipoprotein (LDL)? ?

Of the following cell types, the greatest concentration of high-density lipoprotein (HDLs) would be associated?

Q. Of the following cell types, the greatest concentration of high-density lipoprotein (HDLs) would be associated with ________ cells
A) skin
B) muscle
C) connective tissue
D) blood
E) liver

A. Though these proteins that transport cholesterol are in the blood...
the liver is the one that makes this cholesterol, if it isn't obtained
from the foods we eat.

The LDL, which is considered the bad cholesterol...is the lipo
protein that transport cholesterol out from the liver to the cells
and is known to clog the arteries.

The HDL is the lipo protein that transports
cholesterol back to the liver...so since it is the HDL....
then I believe the answer would be the liver (E).

This seems kind of tricky...considering the cholesterol
is transported in the blood...so it might also be D) Blood
since blood tests are taken to determine how much
HDL and LDL are present.

Hope this has been of some help. Best wishes

Where is Low density lipoprotein (LDL) & High density lipoprotein (HDL) synthesized?
Q. Could you also let me know
1. HOW and WHERE they are removed from the bloodstream and
2. Dietary and lifestyle factors that may increase or decrease the amount in the blood (please explain).

I have been researching but I didn't find much.

A. Mostly the liver makes LDL and HDL which are fats/cholesterol..
You can stop eating cholesterol for the rest of your life and still have high levels. How can this be? For starters, all of your cells can create cholesterol. This is good because every cell in your body needs it to form protective membranes. Your body actually monitors your cells, and if it senses that a cell doesn't have enough cholesterol, it will produce more. Cholesterol also is an essential building block for naturally produced vitamin D and other good stuff, like estrogen and testosterone. But even though every cell can make its own cholesterol, some cells need extra help with their supply. This is where your liver comes in.
Your body, mainly your liver, produces 75 percent of your cholesterol; your small intestine also aids in both the creation and absorption of cholesterol [source: AHA]. The average diet adds another 300 to 500 mg of cholesterol [source: Schafer]. This external cholesterol comes from animal and dairy products. But even if you eat foods without cholesterol, the carbs, fats and proteins all break down eventually and release carbon, which your liver turns into cholesterol.

Q. Could you also let me know
1. HOW and WHERE they are removed from the bloodstream and
2. Dietary and lifestyle factors that may increase or decrease the amount in the blood (please explain).

A. HDL cholesterol "scavenges" your bad cholesterol and helps to eliminate LDL from the body. The only nonpharmacologic way to increase your HDL is to exercise.

Ingesting more soluble fiber lowers your LDL cholesterol because soluble fiber binds bile in the GI tract and it gets eliminated. Bile is synthesized using LDL, so that's why you sometimes see advertising on the side of quaker oats that they can lower your cholesterol. I believe the recommendation is to get 20-30 g of fiber / day.

Why is cholesterol important for your health and the function of your body?

Q. Why is cholesterol important for your health and the function of your body? Is cholesterol in your diet really that bad?

A. Cholesterol doesn't make you fat or anything, but it contributes to heart disease in the future. If you have a high cholesterol, you have a high chance of heart disease. To prevent this, try eating mono-unsaturated fats, and poly-unsaturated fats. These are good fats that lower bad cholesterol, and increase your good cholesterol. Sources of mono and poly unsaturated fats are nuts - almonds, pecans, peanuts, and walnuts, and cooking oil, lol.

When does cholesterol synthesis occurs during the night, or whenever one goes to sleeps?
Q. -Statins are suggested to be taken at night when cholesterol synthesis occurs most. But does this process occurs during the daytime as well, when certain individuals goes to sleep (such as those with overnight working schedules), or does synthesis occur when there is very little or no sunlight present?

A. Where do I ask a question?

How many mg of cholesterol can you have per day if you have high cholesterol?
Q. Some websites say 300 mg and some say 200 mg. Which one is correct?

This is for people with a high cholesterol level btw.

A. I checked too, and i read that if your cholesterol is 5,2 - 6,5 mmol/l then you can have 300 mg per day
If the cholesterol is 6,5 - 7,8 mmol/l then you can have 200mg per day.
if the cholesterol is up to 7,8 mmol/l then you can have 150 mg / day

I hope it helps!

What is the difference between a triglyceride and a phospholipid?

Q. What is the difference between a triglyceride and a phospholipid? How does this difference account for the hydrophobic and hydrophilic nature of phospholipids?

A. I'm doing this at A-level now, are you?

We did this today...

A Phospholipid is Glycerol + 2 Fatty acids + 1 Phosphoric Acid

In a condensation reaction, this produces 1 phospholipid, and 3 water molecules.

The phosphate part of this has OH groups, which can form hydrogen bonds with water.
The fatty acid parts don't have Oh groups, so they are hydrophobic.

A triglyceride is made up of glycerol + 3 fatty acids (the phosphoric acid is replaced by another fatty acid, in comparison to the formula for phospholipid).

Because the phosphate part contained the OH group in the phospholipid, and it is absent in this molecule, triglyceride can not form hydrogen bonds, and so is hydrophobic.

hope this helps, i know research can be tricky, often there's either not enough, or too much more advanced information.

why would chylomicron, low-density lipoprotein, and high-density lipoprotein form a spherical shape?

Q. not sure if this is important:
chylomicron has 4% phospholipid, 90% triacylglycerol, 5% cholesterol, 1% protein.
low-density lipoprotein has 20% phospholipid, 10% triacylglycerol, 45% cholesterol, 25% protein.
high-density lipoprotein has 30% phospholipid, 5% triacylglycerol, 20% cholesterol, 45% protein.

A. Particles (and systems in general) always follow the "principal of least energy" which reduces the free energy of a system to minimum.

Phospholipids are polar compounds based upon a glycerol backbone. Two fatty acids are attached to the phospholipid at the sn-1, and sn-2 position (end and middle respectively). Both fatty acids are non-polar and hydrophobic (water-hating). The third spot is taken by a polar group at the sn-3 position (e.g. the other end) which is hydrophilic (water loving). In addition to polar amino acids and proteins, the outer side of the lipoprotein particles face the water while the hydrophobic portions point inward, where triglycerides, cholesterol and cholesterol esters are.

The hydrophilic outer portion allows lipoprotein particles to stay suspended in serum and blood. The inner lipid and sterol portion attract each other and form a stable system.

The shape that reduces free energy to a minimum is a sphere so lipoprotein particles assume that shape.

Without the phospholipids and proteins surrounding the water-insoluble portions, the lipid and sterol molecules would simply coalesce, which would result in blobs of fat accumulating in the circulatory system.

Is there a Low density lipoprotein(LDL) and High density lipoprotein (HDL) reader available in the market?
Q.

A. LDL and HDL are determined by Photometry method in a Pathological Laboratory.You are required to give a blood sample for this.
Full Blood profile consists of TC,HDL,TG and LDL.

Ldl is 196 triglycerides 154 hdl 31 hdl ratio 8 ldl ratio 6.3 very low density lipoprotein 30.8 my age is 44?
Q.

A. LDL- High LDL level, corresponding to much higher rates for developing symptomatic cardiovascular disease events
Triglyceride- Slightly above normal.
HDL- Low HDL cholesterol, heightened risk for heart disease.
VLDL- slightly above normal.
Risk for cardiac disease is assessed by dividing the total cholesterol level by the HDL level. Target values are <5 for men and <4.4 for women.
Take statin drug in consultation with your doctor.
Also control your cholesterol level by diet and exercise. You may also take omega-3 fatty acid (fish oil).
Adopt DASH diet (Mediterranean diet). Eat a low-cholesterol, low-fat diet, which includes cottage cheese, fat-free milk, fish, vegetables, poultry, and egg whites. Use monounsaturated oils such as olive, peanut, and canola oils or polyunsaturated oils such as corn, safflower, soy, sunflower, cottonseed, and soybean oils. Avoid foods with excess fat in them such as meat (especially liver and fatty meat), egg yolks, whole milk, cream, butter, shortening, pastries, cakes, cookies, gravy, peanut butter, chocolate, olives, potato chips, coconut, cheese (other than cottage cheese), coconut oil, palm oil, and fried foods.

I would like know about high density lipoprotein cholesterol range?

Q. High Density Lipoprotein Cholesterol (HDL-C) is known as "good" cholesterol, so if we have high HDL- C that is better for our hearts. But I don't know how high HDL-C is good. For example, my brother is 47years old. His HDL-C is 82mg/dl. I wonder it is good? Would you please help me to find out the answer. Thank you very much for your time.

A. 60 mg/dL or higher- is considered protective against heart disease.
Less than 40 mg/dL for men- is too low
Less than 50 mg/dL for women- is too low
Of course too low is a major risk factor for heart disease
So, with this guideline set by the American Heart Association even...Your brother is doing just wonderfully. Good Luck!!

Q. Why is cholesterol important for your health and the function of your body? Is cholesterol in your diet really that bad?

A. Cholesterol doesn't make you fat or anything, but it contributes to heart disease in the future. If you have a high cholesterol, you have a high chance of heart disease. To prevent this, try eating mono-unsaturated fats, and poly-unsaturated fats. These are good fats that lower bad cholesterol, and increase your good cholesterol. Sources of mono and poly unsaturated fats are nuts - almonds, pecans, peanuts, and walnuts, and cooking oil, lol.

When does cholesterol synthesis occurs during the night, or whenever one goes to sleeps?
Q. -Statins are suggested to be taken at night when cholesterol synthesis occurs most. But does this process occurs during the daytime as well, when certain individuals goes to sleep (such as those with overnight working schedules), or does synthesis occur when there is very little or no sunlight present?

A. Where do I ask a question?

How many mg of cholesterol can you have per day if you have high cholesterol?
Q. Some websites say 300 mg and some say 200 mg. Which one is correct?

This is for people with a high cholesterol level btw.

A. I checked too, and i read that if your cholesterol is 5,2 - 6,5 mmol/l then you can have 300 mg per day
If the cholesterol is 6,5 - 7,8 mmol/l then you can have 200mg per day.
if the cholesterol is up to 7,8 mmol/l then you can have 150 mg / day

How much Cholesterol should you be taking in every day?

Q. I started reading food labels, and I noticed there's a line called Cholesterol with a number in mg's. How many mg's or what is the total amount of cholesterol per day that is recommended for a 20 something female? Thanks.

A. Officially, experts say you shouldn't have over 300mg (based on a 2,000 calorie diet). I tend to think that's a little high and try to not go over half that. It really depends on your age and activity level. Maybe the link below will help a little more.

How much cholesterol is in egg whites as opposed to the yolks?
Q. One of my co-workers told me that there are equal amounts of cholesterol in both the white and the yolk.

I told her that wasn't true because the yolk is what has all the calories, fat, and cholesterol in it, so I'm doing a good thing by eating egg white omelettes, as opposed to regular ones that include the yolk.

Or am I? Who's right?

A. Your coworker is an idiot. There is zero cholesterol in the white.

But the yolk has good stuff, too, like iron and omega fatty acids, so don't skip it all the time.

How much cholesterol should the average person allow in their diet a day?
Q. Also my Cholesterol is 225, does that mean I should have less than the average person? How much is the right amount?
They did not tell me what my good cholesterol vs my bad cholesterol is but im concerned with how much intake I should allow.

A. Hi MaggieMay,

Itâs currently recommended, for individuals with normal cholesterol levels, to limit dietary cholesterol intake to 300 mg or less daily. If you have high LDL cholesterol, the current recommendations are to limit dietary cholesterol to 200 mg or less per day.

How do you define a triglyceride that has an equal number of mono and polyunsaturated fatty acids?

Q. If a triglyceride has three fatty acids, and one is saturated, one is monosaturated, and one polyunsaturated, how do you define it. Is it overall poly or mono unsaturated, or can you only term it to be unsaturated since they are both equal?

A. a triglyceride can only be saturated or unsaturatedso even if you had one monounsaturated fa it would be classed unsaturated

What is the best way to reduce the triglyceride levels without damaging the liver by taking Lopid?
Q. My triglyceride levels are up to 450. I am not obese I just don't exercise at all. I have been getting away from carbs all together, is that good?

A. These web sites give more information http://www.healingdaily.com/conditions/triglycerides.htm and http://cholesterol.freesourcenow.com/triglyceride-levels.html

What is the difference between a triglyceride and a phospholipid?
Q. What is the difference between a triglyceride and a phospholipid? How does this difference account for the hydrophobic and hydrophilic nature of phospholipids?

A. I'm doing this at A-level now, are you?

We did this today...

A Phospholipid is Glycerol + 2 Fatty acids + 1 Phosphoric Acid

In a condensation reaction, this produces 1 phospholipid, and 3 water molecules.

The phosphate part of this has OH groups, which can form hydrogen bonds with water.
The fatty acid parts don't have Oh groups, so they are hydrophobic.

A triglyceride is made up of glycerol + 3 fatty acids (the phosphoric acid is replaced by another fatty acid, in comparison to the formula for phospholipid).

Because the phosphate part contained the OH group in the phospholipid, and it is absent in this molecule, triglyceride can not form hydrogen bonds, and so is hydrophobic.

hope this helps, i know research can be tricky, often there's either not enough, or too much more advanced information.

How to induce Low density lipoprotein or bad cholesterol levels on rabbits please?

Q.

A. Estrogens induce low-density lipoprotein receptor activity and decrease intracellular cholesterol in animals hepatoma cell line Hep G2.

A new reagent effective in inhibiting cholesterol synthesis 75% in human fibroblasts derived from patients suffering from the disease familial hypercholestrolemia is mannose-6-phosphate-low density lipoprotein and is effective in tissue culture test systems at 100 μg/ml after a ten-hour exposure. The broad purpose of this invention is to modify the receptor specificity of a protein so that it will enter cells which were previously impermeable and exert new effects or reverse a pathological condition. Toxins may also be modified in this manner producing cell type specific and tumor suppressive reagents which are effective in a dose range of 0.3-3 μg. The object here is to use the reagent to selectively kill one cell type which is exerting a pathological effect without affecting normal cells. Among others to which this invention is applicable are Man6P-low density lipoprotein, Man6P-ricin, Man6P-Modeccin, anti Thy 1.2 monoclonal antibody-ricin and anti Thy 1.1 monoclonal antibody-ricin.

Take care always!

How are low density lipoproteins related to health, diet, and cholesterol?
Q. I need the answer by tonight

A. Good cholesterol is high density lipoproteins (HDL) and bad cholesterol is low density lipoproteins (LDL).

Unsaturated fats (most vegetable fats such as nuts, beans, peas and lentils) will increase your HDL level, decrease your LDL level and also reduce your overall cholesterol.

Saturated fats are mostly LDL.

what is LOW DENSITY LIPOPROTEIN RECEPTOR GENE and what does it do?
Q. i was just wondering what it is.. it doesn't need to be detailed or anything, just a simple english answer

A. I believe that a Low Density Lipoprotein receptor gene is a gene that makes an individual more susceptible to accumulating LDL in their bloodstream. As a side note, LDL is the so called "bad" cholesterol that can stick to fats and cause a blockage in the body.

where is Low density lipoprotein (LDL) & High density lipoprotein (HDL) synthesized?

Q. Could you also let me know
1. HOW and WHERE they are removed from the bloodstream and
2. Dietary and lifestyle factors that may increase or decrease the amount in the blood (please explain).

I have been researching but I didn't find much.

A. HDL cholesterol "scavenges" your bad cholesterol and helps to eliminate LDL from the body. The only nonpharmacologic way to increase your HDL is to exercise.

Ingesting more soluble fiber lowers your LDL cholesterol because soluble fiber binds bile in the GI tract and it gets eliminated. Bile is synthesized using LDL, so that's why you sometimes see advertising on the side of quaker oats that they can lower your cholesterol. I believe the recommendation is to get 20-30 g of fiber / day.

why would chylomicron, low-density lipoprotein, and high-density lipoprotein form a spherical shape?
Q. not sure if this is important:
chylomicron has 4% phospholipid, 90% triacylglycerol, 5% cholesterol, 1% protein.
low-density lipoprotein has 20% phospholipid, 10% triacylglycerol, 45% cholesterol, 25% protein.
high-density lipoprotein has 30% phospholipid, 5% triacylglycerol, 20% cholesterol, 45% protein.

A. Particles (and systems in general) always follow the "principal of least energy" which reduces the free energy of a system to minimum.

Phospholipids are polar compounds based upon a glycerol backbone. Two fatty acids are attached to the phospholipid at the sn-1, and sn-2 position (end and middle respectively). Both fatty acids are non-polar and hydrophobic (water-hating). The third spot is taken by a polar group at the sn-3 position (e.g. the other end) which is hydrophilic (water loving). In addition to polar amino acids and proteins, the outer side of the lipoprotein particles face the water while the hydrophobic portions point inward, where triglycerides, cholesterol and cholesterol esters are.

The hydrophilic outer portion allows lipoprotein particles to stay suspended in serum and blood. The inner lipid and sterol portion attract each other and form a stable system.

The shape that reduces free energy to a minimum is a sphere so lipoprotein particles assume that shape.

Without the phospholipids and proteins surrounding the water-insoluble portions, the lipid and sterol molecules would simply coalesce, which would result in blobs of fat accumulating in the circulatory system.

Is there a Low density lipoprotein(LDL) and High density lipoprotein (HDL) reader available in the market?
Q.

A. LDL and HDL are determined by Photometry method in a Pathological Laboratory.You are required to give a blood sample for this.
Full Blood profile consists of TC,HDL,TG and LDL.

I would like know about high density lipoprotein cholesterol range?

Q. High Density Lipoprotein Cholesterol (HDL-C) is known as "good" cholesterol, so if we have high HDL- C that is better for our hearts. But I don't know how high HDL-C is good. For example, my brother is 47years old. His HDL-C is 82mg/dl. I wonder it is good? Would you please help me to find out the answer. Thank you very much for your time.

A. 60 mg/dL or higher- is considered protective against heart disease.
Less than 40 mg/dL for men- is too low
Less than 50 mg/dL for women- is too low
Of course too low is a major risk factor for heart disease
So, with this guideline set by the American Heart Association even...Your brother is doing just wonderfully. Good Luck!!

How is the high density lipoprotein formed? And where specifically?
Q. Where does it come from?

A. It is made mainly near the blood vessels around the body, but the precursors come from the liver.

http://www.nature.com/nrd/journal/v4/n3/fig_tab/nrd1658_F2.html

There are a few sources with handy diagrams

How does HDL (High density lipoprotein) reduce the risk of atheroma formation,and Coronary Heart Disease?
Q. and what is the effect of low concentration of HDL inside the blood?

A. HDL carries cholesterol from the body tissues to the liver.

Lower HDL levels result in more cholesterol in blood leading to increased risk of atheroma formation,and Coronary Heart Disease.

Do you have hyperlipidemia or high cholesterol ? How old are you ?

Q. I'm in my mid-30's and my triglycerides and cholesterol are high. Please share your experience.

A. I'm 48 and mine were high, too. My doctor gave me three months to try to get it down on my own. I went on a no-fat diet...nothing fried, no red meat. no butter or margarine. Fish, nuts and olive oil are OK because they have the healthy kind of fat. Foods only steamed, grilled, etc. No more sauteed Chinese food! In three months, I got my total cholesterol down 100 points and triglycerides down 75 points, both now in a good range so I don't need medicine. You can do it! It does take discipline.....I didn't cheat. Also, I lost weight from this diet.

If someone has hyperlipidemia, how soon after a blood draw can you see the lipids in their blood?
Q. I'm doing a case study on a patient with hyperlipidemia, among other things, and I found a photo of a vial of blood showing the lipids sitting at the top of the vial. It states that this photo was taken 4 hrs after the blood was drawn & I'm wondering if it has to sit for that long to be visible?

A. It is correct as soon as the blood starts to separate and settle or clot and separate, which begins immediately in around a half an hour you have pretty good separation, but we don't spin the blood down for 30 minutes (not when you need to get a result out in an hour)-5-10 minutes is more like it.

Do i have hyperlipidemia and obesity?
Q. so it wasnt long ago when i got blood out of me. i got a letter from the mail today saying im referred to a cardiology and nutritionist, and the near middle it saids this:
"Diagnosis: Obesity, Hyperlipidemia" , So do i have hyperlipidemia and obesity. Best Answer Get Max Points. Thank you for responding.
So by you saying yes i do have it but it can be diagnosis.

A. Hyperlipidemia is just a fancy name for high cholesterol. So, you are apparently overweight and have high cholesterol - these two things usually occur together and both are usually diet-related.

Can triglyceride levels in dogs increase from the chewing/eating of rawhide?

Q. I have increased the amount of rawhide chews I give to my Beagle, and coincidentally, her triglycerides soared. Is there any connection between the two? Otherwise, she is fed Nutro Ultra for Seniors dry mixed with a little bit of canned and water for a sauce. She is not fed fats, and has a healthy diet of fruits and veggies for snacks.

A. most raw-hides are deep fried or oven basted with chicken fat as dripping, so are just full of fat. You can get healthier ones if you search, but they cost more. Most people recommend the nylon bones, but I have heard if they are too small the dogs can swallow them whole, then you will need an operation.

I give my dogs a small healthy meaty bone to chew daily, its part of their breakfast calorie, is natural and much lower in fat.

Why is a triglyceride considered hydrophobic when it has a glycerol molecule which is hydrophilic?
Q. also- can everything be categorized as hydrophilic and hydrophobic?

lastly- if the outside of our membranes is hydrophilic wouldn't we dissolve in water?

A. The hydroxyl group of glycerol joins in an ester linkage with the carboxyl group on the lipid leaving a hydrophilic compound.

Not all compounds are one or the other some are amphiphilic with a polar hydrophilic end and a nonpolar lipophilic hydrocarbon end like the phospholipids in cell membranes.

What type of triglyceride would vegetable oil, butter and shortening be?

A. Butter- the good kind.
Vegetable oil and shortening- the bad kind.
Canola oil is much better for you than vegetable oil. :))

What can I do as a woman after menapause do to improve on my Cholesterol and Triglyceride blood results?

Q. In April 2006 my blood work showed: Cholesterol 167.6; Triglyceride 220.4 and HDL 38.1. I am talking Lipitor during both of these blood tests.
In October 2006 my blook work showed: Cholesterol 211.1; Triglyceride 143.7 and HDL 48.5.
I listed the HDL because I was afraid the Lipitor was effecting my Good Cholestrol count.
I'm looking for someone that can tell me why my cholestrol went up this time and triglycerides went down and what is my next course of action.

A. Eat cabbage, oatmeal, apples, etc. for soluble fiber and of course some type of exercise.

Also, here's some all-natural supplements that are very effective.

OmegaGuard: reduces the risk of heart disease/stroke, lowers triglycerides and cholesterol

Soluble Fiber (e.g. Fiber Plan): prevents fat absorption; reduces stress on heart by minimizing fat accumulation

Lecithin: converts serum cholesterol to good HDL

CoQHeart: Reduces LDL oxidation

Garlic Complex: prevents clotting; dilates small blood vessels; dissolves fatty deposits & thins blood

Hope this is useful and feel free to contact me with questions.

What determines whether a triglyceride is saturated or unsaturated?
Q. Is it the bonds?

A. A trigylceride (fat) is basically a glycerol molecule joined to three fatty acid molecules. The fatty acid molecules are often called "fatty acid chains" or "fatty acid tails".

Triglyceride structure:
http://www.indiana.edu/~oso/Fat/FatImg/triglyceride.jpg

If a triglyceride contains fatty acid tails with only single bonds in their structure, it is said to be saturated (saturated with hydrogens - it contains the maximum no. of C-H bonds).

If a triglyceride contains one or more fatty acid tails which contain at least one double bond in their structure, it is said to be unsaturated.

Here is a pic which shows the difference between saturated and unsaturated fats:
http://www.realfitnessblog.com/wp-content/uploads/2008/11/fat_f2.jpg

As the pic above shows, saturated fats are usually straight, so the molecules can pack together tightly, which is why saturated fats are solids at room temp. The double bonds in the structure of unsaturated fats makes kinks in the chain preventing the neat packing together of these molecules, so most unsaturated fats are liquids at room temp.

What is the function of Triglyceride and Phospholipid?
Q. Also, what are some examples of nucleic acids besides DNA and RNA?

Thanks!

A. Triglycerides and Phospholipids are present in the Plasma Membrane of the cell to make each cell regionally distinct from one another.

how do high density lipoprotein leads to diabetes?

Q. how do high density lipoprotein leads to diabetes?
what are the scientific theory behind it?

A. high density lipoproteins DO NOT lead to diabetes! HDL is the "good" cholesterol --- your question is totally wrong!

Type 2 is not "caused" by being overweight! Many factors are involved in the development of type 2 DM, including genetics, lifestyle, and medications. the idea that being overweight causes type 2 DM is an unfortunate piece of information, Obesity is a risk factor but is NOT the cause!

Of the following cell types, the greatest concentration of high-density lipoprotein (HDLs) would be associated?
Q. Of the following cell types, the greatest concentration of high-density lipoprotein (HDLs) would be associated with ________ cells
A) skin
B) muscle
C) connective tissue
D) blood
E) liver

A. Though these proteins that transport cholesterol are in the blood...
the liver is the one that makes this cholesterol, if it isn't obtained
from the foods we eat.

The LDL, which is considered the bad cholesterol...is the lipo
protein that transport cholesterol out from the liver to the cells
and is known to clog the arteries.

The HDL is the lipo protein that transports
cholesterol back to the liver...so since it is the HDL....
then I believe the answer would be the liver (E).

This seems kind of tricky...considering the cholesterol
is transported in the blood...so it might also be D) Blood
since blood tests are taken to determine how much
HDL and LDL are present.

Hope this has been of some help. Best wishes

Where is Low density lipoprotein (LDL) & High density lipoprotein (HDL) synthesized?
Q. Could you also let me know
1. HOW and WHERE they are removed from the bloodstream and
2. Dietary and lifestyle factors that may increase or decrease the amount in the blood (please explain).

I have been researching but I didn't find much.

A. Mostly the liver makes LDL and HDL which are fats/cholesterol..
You can stop eating cholesterol for the rest of your life and still have high levels. How can this be? For starters, all of your cells can create cholesterol. This is good because every cell in your body needs it to form protective membranes. Your body actually monitors your cells, and if it senses that a cell doesn't have enough cholesterol, it will produce more. Cholesterol also is an essential building block for naturally produced vitamin D and other good stuff, like estrogen and testosterone. But even though every cell can make its own cholesterol, some cells need extra help with their supply. This is where your liver comes in.
Your body, mainly your liver, produces 75 percent of your cholesterol; your small intestine also aids in both the creation and absorption of cholesterol [source: AHA]. The average diet adds another 300 to 500 mg of cholesterol [source: Schafer]. This external cholesterol comes from animal and dairy products. But even if you eat foods without cholesterol, the carbs, fats and proteins all break down eventually and release carbon, which your liver turns into cholesterol.

What is the difference between hyperlipidemia and hypercholesterolemia?

Q.

A. Hypercholesterolemia (literally: high blood cholesterol) is the presence of high levels of cholesterol in the blood.
Hyperlipidemia is an elevation of lipids (fats) in the bloodstream. These lipids include cholesterol, cholesterol esters (compounds), phospholipids and triglycerides.
Hyperlipidemia is caused by an elevated level of any kind of lipid (fat) in the blood stream, while hypercholesterolemia is only caused by high cholesterol in the blood stream.

Is there a particular group (ethnicity, sociological culture) that is predisposed for hyperlipidemia?
Q. Is there a particular group (ethnicity, sociological culture) that is predisposed for the condition of hyerlipidemia?

A. Yes; those with a family history of hyperlipidemia since predisposition rests equally on genetic and environmental factors and their interplay.

Another predisposition is use of oral contraceptives (OC) in women; and in people who use antihypertensives, retinoids, and/or hypolipidic agents.

Do you have hyperlipidemia or high cholesterol ? How old are you ?

How is cholesterol good for you and your body?
Q. Explain the benefits of cholesterol for the body and its functions. How does it affect joints and organs?

A. Americans are being saturated with anti-cholesterol propaganda. If you watch very much television, you're probably one of the millions of Americans who now has a terminal case of cholesterol phobia. The probaganda is relentless and is often designed to produce fear and loathing of this works of all food contaminants. You never hear the food propagandists bragging about their product being fluoride free or aluminum free, two of our truly serious food-addidtive problems. But cholesterol, an essential nutrient not proven to be harmfull in ANY quantity is constantly pilloried as a menance to your health. If you don't use corn oil, Fleishmann's margarine and Egg Beaters, you are going straight to atherosclerosis hell with stroke, heart attack and premature aging and so are your kids.

How much Cholesterol should you be taking in every day?
Q. I started reading food labels, and I noticed there's a line called Cholesterol with a number in mg's. How many mg's or what is the total amount of cholesterol per day that is recommended for a 20 something female? Thanks.

A. Officially, experts say you shouldn't have over 300mg (based on a 2,000 calorie diet). I tend to think that's a little high and try to not go over half that. It really depends on your age and activity level. Maybe the link below will help a little more.
