The chemical processes through which the body uses, stores, and circulates lipids and lipoproteins. Lipids are a broad category of substances that includes fats and fatlike compounds such as sterols (including cholesterol). Phospholipids are a group of lipids that constitute an important component of the membranes that surround body cells. Lipoproteins are complex substances made of varying amounts of cholesterol, triglycerides, phospholipids, and protein. Apolipoproteins are the protein components of lipoprotein complexes. Because they are not soluble in water, lipids such as fats and cholesterol are carried in the blood in the form of lipoproteins. Fats are used for energy or stored in fat cells. Cholesterol is not used for energy, but as a building block for a wide range of compounds such as bile, estrogen, testosterone, and vitamin D.<\/p>\n
