| HCTS | high cholesterol and tocopherol supplement |
| cholesterol esterase | <enzyme> An enzyme that catalyses the hydrolysis of cholesterol and some other sterol esters, to liberate cholesterol plus a fatty acid anion. Chemical name: Steryl-ester acylhydrolase Registry number: EC 3.1.1.13 (12 Dec 1998) |
|---|---|
| cholesterol esters | Fatty acid esters of cholesterol which constitute about two-thirds of the cholesterol in the plasma. The accumulation of cholesterol esters in the arterial intima is a characteristic feature of atherosclerosis. (12 Dec 1998) |
| cholesterol ester storage disease | A rare benign adult form of inherited lysosomal lipid storage disease that is due to deficiency of acid lipase. It results in an accumulation of neutral lipids, particularly cholesterol esters, within cells (particularly leukocytes, fibroblasts, and liver cells). It is an allelic variant of wolman disease. (12 Dec 1998) |
| cholesterol ester transport proteins | A protein that transports cholesterol esters from HDL to VLDL and LDL; a deficiency of this protein is associated with elevated HDL cholesterol. (05 Mar 2000) |
| cholesterol, good | High-density lipoprotein (HDL) cholesterol. (12 Dec 1998) |
| cholesterol, hdl | High-density lipoprotein cholesterol (the good cholesterol). (12 Dec 1998) |
| cholesterol, ldl | Low-density lipoprotein cholesterol (the bad cholesterol). (12 Dec 1998) |
| cholesterol monooxygenase | <enzyme> Multi-enzyme complex required for the conversion of cholesterol to adrenal cortex hormones. It releases methylpentanoate or isocaproaldehyde and pregnenolone. The complex contains cytochrome p-450, a flavoprotein, a non-haem iron protein, and NADPH. Chemical name: Cholesterol,reduced-adrenal-ferredoxin:oxygen oxidoreductase (side-chain-cleaving) Registry number: EC 1.14.15.6 (12 Dec 1998) |
| cholesterol oxidase | <enzyme> An enzyme that catalyses the oxidation of cholesterol in the presence of molecular oxygen to 4-cholesten-3-one and hydrogen peroxide. The enzyme is not specific for cholesterol, but will also oxidise other 3-hydroxysteroids. Chemical name: Cholesterol:oxygen oxidoreductase Registry number: EC 1.1.3.6 (12 Dec 1998) |
| cholesterol reductase | <enzyme> Uses NADH; reduces cholesterol to cholestanol (coprostanol) Registry number: EC 1.3.1.- (26 Jun 1999) |
| cholesterol sulfotransferase | <enzyme> Transfers sulfate from paps to cholesterol Registry number: EC 2.8.2.- (26 Jun 1999) |
| hdl cholesterol | High-density lipoprotein cholesterol (the good cholesterol). (12 Dec 1998) |
| NAD(P)+-dependent cholesterol dehydrogenase | <enzyme> Oxidises the 3 beta-oh group of cholesterol to cholestenone in the presence of NADP+ Registry number: EC 1.1.1.- Synonym: NADP+-dc-dehydrogenase, cholesterol 3-dehydrogenase (26 Jun 1999) |
| i-cholesterol isomerase | <enzyme> 7-hydroxy group is isomerised to position 3 on ring a to form cholesterol Registry number: EC 5.4.99.- (26 Jun 1999) |
| embolism, cholesterol | An embolism of lipid debris from an ulcerated atheromatous deposit, generally from a large artery to small arterial branches. It is usually small and rarely causes infarction. (12 Dec 1998) |
