Cholesterol is a lipid that is the "principal sterol of all higher animals, distributed in body tissues, especially the brain and spinal cord, and in animal fats and oils."[1]

Disorders of cholesterol

Hypercholesterolemia may contribute to coronary heart disease, stroke, and other complications. Hypercholesterolemia may be treated by medications such as statins, bile acid sequestrants, fibric acid derivatives, and plant stanols.
