| 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) |
| cholesterol, bad | Low-density lipoprotein (LDL) cholesterol. (12 Dec 1998) |
