Made of 3 fatty acids attached to a glycerol backbone. Hel p in carrying out digestion, absorption, and transport of lipids. Normal level in blood: <200 mg/100 ml. Too much: plaque atherosclerosis coronary heart disease. In meat and dairy products (exogenous cholesterol: coronary artery supplies blood to heart.
