| lipoproteins, hdl cholesterol | Cholesterol which is contained in or bound to high density lipoproteins (hdl). High density lipoproteins transport cholesterol from peripheral tissues to the liver thereby acting as a scavenger to prevent excess accumulation and deposition of cholesterol in blood vessels. (12 Dec 1998) |
|---|---|
| lipoproteins, ldl cholesterol | Cholesterol which is contained in or bound to low density lipoproteins (ldl). Ldl transport cholesterol to peripheral tissues and regulate de novo cholesterol synthesis at these sites. Atherosclerosis is caused by the deposit of cholesterol on the walls of blood vessels, because of high concentrations of ldl cholesterol in plasma. (12 Dec 1998) |
| lipoproteins, vldl cholesterol | Cholesterol which is contained in or bound to very low density lipoproteins (vldl). High concentrations of vldl cholesterol are found in type IIb and type v hyperlipoproteinaemia. The end product of vldl cholesterol catabolism is ldl (low density lipoproteins). (12 Dec 1998) |
| acetaldehyde oxidase | <enzyme> Acetaldehyde is converted to acetate Registry number: EC 1.2.- (26 Jun 1999) |
| acyl-CoA oxidase | <enzyme> Catalyses stoichiometric conversion of palmitoyl-CoA and o2 into 2-hexadecenoyl-CoA and h2o2; oxidises acyl-CoA's with carbon chain lengths of 4 to 20; most active toward lauroyl-CoA, but not acetyl- or succinyl-CoA Registry number: EC 1.3.3.6 Synonym: fatty acyl CoA oxidase, fatty acyl-coenzyme a oxidase, fatty acid acyl-CoA oxidase, acox, pox1 gene product (26 Jun 1999) |
| adrenaline oxidase | amine oxidase (flavin-containing) |
| aldehyde oxidase | <enzyme> Broad substrate specificity Registry number: EC 1.2.3.1 Synonym: n1-methylnicotinamide oxidase I, n-nitrosoreductase (26 Jun 1999) |
| alternative oxidase | <enzyme> The terminal oxidase in alternative pathway respiration, as seen in plants like sauromatum guttatum (voodoo lily); amino acid sequence for tobacco alternative oxidase (aox1) in first source Registry number: EC 1.- Synonym: aox1 gene product, aox2 gene product, aox3 gene product (26 Jun 1999) |
| alternative oxidase pathway | Pathway of mitochondrial electron transport in higher plants, particularly in fruits and seeds, that does not involve cytochrome oxidase and thus is resistant to cyanide. (18 Nov 1997) |
| amine oxidase | <enzyme> A group of enzymes including those oxidizing primary monoamines, diamines, and histamine. They are copper proteins, and, as their action depends on a carbonyl group, they are sensitive to inhibition by saemicarbazide. Chemical name: Amine:oxygen oxidoreductase (deaminating)(copper-containing) Registry number: EC 1.4.3.6 (12 Dec 1998) |
| amine oxidase (copper-containing) | An oxidoreductase containing copper, and perhaps pyridoxal phosphate, and carrying out the same reaction as amine oxidase (flavin-containing). Synonym: amine oxidase (pyridoxal-containing), diamine oxidase, diamino oxyhydrase, histaminase. (05 Mar 2000) |
| amine oxidase (flavin-containing) | An oxidoreductase containing flavin and oxidizing amines with the aid of O2 and water to aldehydes or ketones with the release of NH3 and H2O2. Acted upon by antidepressants. Synonym: adrenaline oxidase, diamine oxidase, monoamine oxidase, tyraminase, tyramine oxidase. (05 Mar 2000) |
| amine oxidase (pyridoxal-containing) | amine oxidase (copper-containing) |
| arginine oxidase | <enzyme> Catalyses the oxidative deamination from arginine to 2-ketoarginine Registry number: EC 1.4.3.- Synonym: arginine dehydrogenase (26 Jun 1999) |
| arsenite oxidase | <enzyme> Two n-terminal amino acid iron-sulfur protein containing molybdenum; detoxifies arsenite to arsenate Registry number: EC 1.16.- (26 Jun 1999) |
