Cholesterol
Correct! Cholesterol is a waxy, fat-like compound that belongs to a class of molecules called steroids. Cholesterol is found in many foods, in the bloodstream and in all body cells. It is essential for the formation and maintenance of cell membranes and for the formation of sex hormones. Cholesterol is also an important component of bile salts, which help to digest food and aid in the conversion of food into vitamin D in the skin when exposed to sunlight.
