cholesterol
cholesterol A
sterol (see also
steroid) occurring widely in animal tissues and also in some plants and algae. It can exist as a free sterol or esterified with a long-chain fatty acid. Cholesterol is absorbed through the intestine or manufactured in the liver. It serves principally as a constituent of blood plasma
lipoproteins and of the lipid–protein complexes that form plasma membranes. It is also important as a precursor of various steroids, especially the bile acids, sex hormones, and adrenocorticoid hormones. The derivative 7-dehydrocholesterol is converted to vitamin D
3 by the action of sunlight on skin. Increased levels of dietary and blood cholesterol have been associated with
atherosclerosis. However, it is now thought that damage to blood vessels is caused by high levels of low-density lipoproteins (LDLs) in the blood; LDLs are the principal form in which cholesterol is transported in the bloodstream.
