Cholesterol – HDL and LDL

Cholesterol is a soft, waxy substance found among the lipids (fats) in the bloodstream and in all your body’s cells. It’s an important part of a healthy body because it’s used to form cell membranes, some hormones, vitamin D, bile acids and is needed for other functions. Cholesterol and other fats can’t dissolve in the blood. They have to be transported to and from the cells by special carriers called lipoproteins. There are several kinds, but the most important are Low-Density Lipoprotein (LDL or ‘bad’) and High-Density Lipoprotein (HDL or ‘good’). (See LDL Cholesterol and HDL Cholesterol)
