| acetyl | <biochemistry, chemistry> This is the radical of acetic acid, it contains a carbonyl and a methyl group that is single-bonded to the carbon, an oxygen is single-bonded to the carbon, and the carbon has two other bonds to the rest of the molecule. (09 Oct 1997) |
| acetyl-activating enzyme | A ligase that catalyses the reaction of acetate and CoA and ATP to form AMP, pyrophosphate, and acetyl-CoA. A key step in the activation of acetate. Synonym: acetate thiokinase, acetate-CoA ligase, acetyl-activating enzyme, acetyl-CoA synthetase. (05 Mar 2000) |
| acetyl chloride | CH3COCl;a colourless liquid used as a reagent; also corrosive, causing severe burns because of hydrolysis to HCl. (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.
