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).]

cholesterol

(kəˈlɛstəˌrɒl)
n
(Biochemistry) a sterol found in all animal tissues, blood, bile, and animal fats: a precursor of other body steroids. A high level of cholesterol in the blood is implicated in some cases of atherosclerosis, leading to heart disease. Formula: C27H45OH. Former name: cholesterin
[C19: from chole- + Greek stereos hard, solid, so called because first observed in gallstones]

cho•les•ter•ol

(kəˈlɛs təˌroʊl, -ˌrɔl)

n.
a sterol, C27H46O, abundant in animal fats, brain and nerve tissue, meat, and eggs, that functions in the body as a membrane constituent and as a precursor of steroid hormones and bile acids: high blood levels are associated with arteriosclerosis and gallstones.
[1890–95; chole- + Greek ster(eós) solid]

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.

cholesterol

- Comes from Greek words meaning "bile, gall" and "stiff, solid," plus the ending "-ol."

cholesterol

A fatty substance produced and used by the body and ingested in food. High levels of certain types of cholesterol can narrow blood vessels, impairing circulation.
