| coenzyme q10 | <biochemistry> A substance that assists in the oxidation of nutrients within cells to create energy. It is also highly efficient at protecting internal and external cell membranes against oxidation and is sometimes proposed as a complementary therapy to combat AIDS-related conditions. (09 Oct 1997) |
| acetoacetyl-coenzyme A | Intermediate in the oxidation of fatty acids and in the formation of ketone bodies; also formed from two molecules of acetyl-CoA; major role is condensation with acetyl-CoA to form the important beta-hydroxy-beta-methylglutaryl-CoA. Synonym: acetoacetyl-coenzyme A. (05 Mar 2000) |
|---|---|
| acetyl-coenzyme A | <enzyme> Condensation product of coenzyme A and acetic acid, symbolised as CoAS~COCH3; intermediate in transfer of two-carbon fragment, notably in its entrance into the tricarboxylic acid cycle and in fatty acid synthesis. This coenzyme plays a huge role in intermediary metabolism, in which cells synthesise, break down or use nutrient molecules for energy production, growth, etc. Acetyl-coenzyme A synthase is found in bacteria and plants and catalyses the reaction in which acetate enters metabolic pathways and forms acetyl-coenzyme A. Synonym: acetyl-coenzyme A, active acetate. (05 Mar 2000) |
