| RPLC | reverse phase liquid chromatography |
| RT3, | rT3 reverse triiodothyronine |
| RTA | ray tracing algorithm; renal tubular acidosis; reverse transcriptase assay; road traffic accident |
| RTI | respiratory tract infection; reverse transcriptase inhibition |
| cholesterol cleft | A space caused by the dissolving out of cholesterol crystals in sections of tissue embedded in paraffin. (05 Mar 2000) |
|---|---|
| cholesterol dehydrogenase | <enzyme> Converts cholesterol to coprostanol; mechanism given is incorrect for enzyme name Registry number: EC 1.3.- (26 Jun 1999) |
| cholesterol, dietary | Cholesterol present in food, especially in animal products. (12 Dec 1998) |
| cholesterol embolism | 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. Synonym: atheroma embolism. (05 Mar 2000) |
| 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, 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) |
