Cholesterol molecule
Cholesterol,molecular model. Atoms are represented as rods and are colour-coded: carbon (grey),hydrogen (white) and oxygen (red). Cholesterol is a lipid,a fat-like substance,though chemically it is a sterol,a type of alcohol. It is an important cell chemical,and plays a crucial role in the synthesis of bile salts and hormones,and in transporting fats in the bloodstream. High blood levels of LDL (low- density lipoprotein) cholesterol compared to HDL (high-density lipoprotein) cholesterol are thought to raise the risk of atherosclerosis,the build-up of fatty deposits on artery walls. This is a major cause of heart attack and stroke.
