cho·les·ter·ol

 (kə-lĕs′tə-rôl′, -rōl′)
n.
A white crystalline substance, C27H45OH, that is found in animal tissues and various foods and is important as a constituent of cell membranes and a precursor to steroid hormones. Cholesterol is normally synthesized by the liver and is transported through the bloodstream by different types of lipoproteins, two of which (HDL and LDL) are routinely measured in blood tests.

[cholester(in), former name for cholesterol (chole- + Greek stereos, solid; see ster- in Indo-European roots + -in) + -ol (so called because it was first found in gallstones).]

cho·les·ter·ol

(kə-lĕs′tə-rôl′)
A fatty substance found in animals and plants that is a main component of cell membranes and is important in metabolism and hormone production. In vertebrate animals, cholesterol is a major component of the blood. Higher than normal amounts of cholesterol in the blood, which can occur from eating too many fatty foods, may lead to diseases of the arteries such as atherosclerosis.
