Cholesterol,molecular model. 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. Atoms are represented as spheres and are colour-coded: carbon (black),hydrogen (yellow) and oxygen (red) | |
