What is the role of cholesterol on the phospholipid bilayer?
Cholesterol plays a crucial role in maintaining the integrity and fluidity of the phospholipid bilayer in cell membranes. It intercalates between phospholipid molecules, reducing membrane permeability and preventing fatty acid chains from packing too closely together. This helps stabilize the membrane structure, ensuring it remains flexible across varying temperatures. Additionally, cholesterol contributes to the formation of lipid rafts, which are essential for cellular signaling and membrane protein function.

What is a good food source of cholesterol?
I think you are confusing cholesterol that you eat with cholesterol in the blood. Cholesterol in your blood is measured in particles. Some of the particles are LDL, or low density lipoproteins, and HDL, or high density lipoproteins. LDL is referred to as the "bad cholesterol". You can remember it because the "L" that it starts with stands for "lousy", or you want it to be "low". HDL is known as the "good cholesterol". The "H" in HDL can stand for "healthy" or you want it to be "high".
It is not that easy to increase your HDL. LDL can be decreased some with diet, and quite a bit with medication. HDL can be increased with exercise. Medications are not that good at increasing HDL.
The cholesterol that you eat is of only one kind. Cholesterol is only found in animal products. If it didn't come from an animal or have an animal product in it, there is no cholesterol. Lots of food, on the other hand, have fat. There are several kinds of fat. The best fats are monounsaturated fats and omega 3 fatty acids. You can find monounsaturated fats in things like olive oil, canola oil, olives, nuts, and avocado. Omega 3 fatty acids are found in foods like fish, walnuts, and flax seed.
In general, the fats that you should limit are fats that are solid at room temperature. For example, butter, margarine, shortening, and animal fat are all solid at room temperature. They can still be part of a healthy diet, but should be eaten in moderation. One last note; in terms of calories, all fats are equal. Fat, no matter what kind, has 9 calories per gram. Fat is the most calorie dense nutrient.
Which foods should a person with high cholesterol levels avoid?

LDL is often referred to as bad cholesterol because it can build up in the wall of the arties, causing a risk of cardiovascular problems. HDL is often referred to as the good cholesterol because it helps remove LDL from the arteries.
How much cholesterol is needed in the body?
The body needs no dietary source of cholesterol, as this substance is able to be made by the liver using other oils in the diet.
What are the causes of high cholesterol?
Fatty foods can cause this so you may what to eat correctly...
Animals produce cholesterol in their bodies. Cholesterol moves nutrients throughout the body, via the blood stream. Dietary cholesterol comes from consuming animals or animal products.
A solid compound in blood; a steroid alcohol sterol made by the liver and present in all animal cells.
Cholesterol is a lipid, is the most plentiful steroid found in animal tissue and is an important component to the human body. It is manufactured in the liver and carried throughout the body in the bloodstream. It's required to build and maintain membranes, aids in absorption of fat soluble vitamins, precursor of vitamin D and steroid hormones (cortisol, aldosterone, prgesteron, estrogen and testosterone).
collestoll problem?
Mainly insoluble in drinking water, it travels within the blood stream by means of lipoproteins. At first, it really is carried through the intestinal mucosa towards the liver within chylomicrons. Within the liver it really is changed into low-density lipoprotein (LDL) in order to carries cholesterol towards the cells, whilst high-density lipoprotein (HDL) bears it returning to the liver for removal.
It really is interesting to notice that this cholesterol in BAD cholesterol and also the cholesterol within HDL cholesterol are similar. The only real difference between two may be the carrier chemical (i. e. the actual lipoprote.)
Cholesterol is stereos. This is what makes up organic molecule.
Cholesterol is a substance produced by the liver and is in certain foods. There are two kinds of cholesterol HDL and LDL. LDL is the good kind.
What's the most effective diet to lower cholesterol?
A very effective way of lowering your cholesterol is by simply switching over to a vegetarian diet. If you can't seem to do this, you may want to consider becoming a pescotarian, abstaining from all meat except for a occasional meal of fish or seafood (watch out, though, as lobster, shrimp, and other seafood have very high levels of cholesterol).
The vegetarian diet generally reduces the amount of cholesterol in the blood stream, but also has a whole host of other health benefit. A study by M. Segasothy and P.A. Phillips called "Vegetarian diet: panacea for modern lifestyle diseases?" published in Oxford's Quarterly Journal of Medicine, clearly indicates that there is much to be gained from the vegetarian diet.
"Soy-bean-protein diet, legumes, nuts and soluble fibre significantly decrease total cholesterol, low-density lipoprotein cholesterol and triglycerides. Diets rich in fibre and complex carbohydrate, and restricted in fat, improve control of blood glucose concentration, lower insulin requirement and aid in weight control in diabetic patients. An inverse association has been reported between nut, fruit, vegetable and fibre consumption, and the risk of coronary heart disease. Patients eating a vegetarian diet, with comprehensive lifestyle changes, have had reduced frequency, duration and severity of angina as well as regression of coronary atherosclerosis and improved coronary perfusion. An inverse association between fruit and vegetable consumption and stroke has been suggested. Consumption of fruits and vegetables, especially spinach and collard green, was associated with a lower risk of age-related ocular macular degeneration."
And the abstract goes on to list more. A study aptly titled "Cardiovascular disease risk factors in free-living men: comparison of two prudent diets, one based on lactoovovegetarianism and the other allowing lean meat" from The American Journal of Clinical Nutrition also provides evidence that supports the vegetarian diet as a cholesterol suppressor. Although both lacto ovo vegetarians (those vegetarians who abstain from meat but eat dairy and eggs) and lean-meat eaters had an overall reduction in cholesterol, "The LOV diet had a significantly greater cholesterol-lowering effect than did the LM diet (10% vs 5% decrease)…"

Where is cholesterol synthesized?
The body's cholesterol is manufactured in the liver.
It is used in the liver to make bile acids where they are then stored in the gall bladder. Bile acids are used to dissolve fats from the food.
In addition, you should know,
Total cholesterol is composed of HDL and LDL. One is "good" cholesterol, and the other is bad.
Bad cholesterol is made when the diet consists of too many fried foods and preferring well-done proteins, not simply because of saturated fats.
It is best to roast, stew, boil or steam meats, or grill to medium only. Eggs should be soft boiled or soft scrambled.
Bad cholesterol is also made from trans fats in diet, and also too many refined carbohydrates.
The goal is to have as much as possible of the "good" cholesterol, even if that means your total cholesterol number reaches 350. Thousands of Eskimo indians have demonstrated it's the healthiest range of total cholesterol.
Beware of statin drugs, they also have plenty of "side" effects.
