| 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) |
