+ Hypercholesterolemia, Cholesterol: Diseases and disorders of the cardiovascular system :: Diseases
  * Cholesterol is a molecule in cells. It is a type of lipid which is a fat or fat-like molecule. Cholesterol is a special type of lipid that is called a steroid. Steroids are lipids that have a special chemical structure. This structure is made of four rings of carbon atoms
  - What does it do?
  * Cholesterol does many important jobs in a cell. Cholesterols main function is as a structural component of cell membranes. It is also the starting material for bile acids that are made by the liver and used to digest fats, and for steroid hormones. However, it is best known for something bad that it does. High levels of cholesterol can lead to atherosclerosis. This is an inflammatory disease of artery walls in which white blood cells invade the vessel wall and become engorged with cholesterol and other lipids.
  * Cholesterol' is a molecule that is found in animal cells and body fluids. Cholesterol is not found in plant sources. It is a type of lipid which is a fat or fat-like molecule. Cholesterol is a soft waxy substance. Cholesterol is a special type of lipid that is called a steroid. Steroids are lipids that have a special chemical structure. This structure is made of four rings of carbon atoms. Cholesterol is found especially in animal fats
  - Where does it come from?
  * Cholesterol is usually in the walls of cells. It is 'only' in animals. Plants do not synthesize cholesterol. So the cholesterol in the food people eat can only come from eating food from animals. But even vegans who eat 'only' plant foods can have cholesterol. This is because 'most' of the cholesterol that is in our bodies is synthesized 'by' our bodies
