Before looking at how cholesterol can be lowered, it is important to understand what it is. It’s not inherently “bad.” Your body needs it to build cells and make vitamins and other hormones.

Cholesterol plays a role in normal cell and body function. The plasma membrane is a continuous double-layer of phospholipids, interweaved with cholesterol and proteins. This may cause blockage to the arteries and heighten the risk of heart attack. High cholesterol causes plaque (fatty deposits) to build up in your blood vessels. The cholesterol molecule has both a hydrophobic and a hydrophilic section which influences its function. Our immune cells base on cholesterol to fight against infections and repair themselves after the fight. -The structure of the tetracyclic ring of cholesterol contributes to the fluidity of the cell membrane, as the molecule is in a trans conformation making all but the side chain of cholesterol rigid and planar.-In this structural role, cholesterol also reduces the permeability of the plasma membrane to neutral solutes,hydrogen ions, and sodium ions. Instead of a single kind of particle, HDL cholesterol … But too much cholesterol can pose a problem. The modulatory role of cholesterol in the function of a number of membrane proteins is well established. The main function of cholesterol is to provide a protective barrier. Furthermore, LDL-cholesterol, also called bad cholesterol, directly binds and immobilizes dangerous bacterial toxins, halting them from doing any damage in the body. Phospholipids are composed of two fatty acids attached to a phosphate compound as a head. In its pure state it is a white, crystalline substance that is odourless and tasteless.

This effect has been proposed to occur either due to a spec … Although one type of plaster -- cholesterol -- has earned more bad press than child actors, the judgment isn't really fair. Although the main molecule making up membranes is the phospholipids, cholesterol is also a crucial component of the structure. HDL cholesterol is turning out to be a much more complex substance than we once believed. Cholesterol is an essential component of eukaryotic membranes and plays a crucial role in membrane organization, dynamics and function. HDL is considered good for health so is termed as good cholesterol. Cholesterol is needed by your body to make new cells. The function of good cholesterol is to transport cholesterol from the arteries and tissues to the liver and other organs such as ovary, adrenal glands, and testis. Cholesterol is main component of cells, which exists in every cell all over the body. 3. Cholesterol provides protective barrier for the cells. Cholesterol is an extremely important biological molecule that has roles in membrane structure as well as being a precursor for the synthesis of the steroid hormones, the bile acids, and vitamin D.Both dietary cholesterol, and that synthesized de novo, are transported through the circulation in lipoprotein particles. Cholesterol is also necessary to the normal permeability and function of the membranes that surround cells. Your body needs some cholesterol to function properly. Cells need cholesterol. Cholesterol is a waxy substance. Our bodies need some cholesterol to function normally and can make all the cholesterol it needs.
