| 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 chloride | CH3COCl;a colourless liquid used as a reagent; also corrosive, causing severe burns because of hydrolysis to HCl. (05 Mar 2000) |
| acetyl CoA carboxylase phosphatase | <enzyme> Phosphatase occurs in complex with the carboxylase Registry number: EC 3.1.3.- Synonym: acc-phosphatase, acetyl coenzyme a carboxylase phosphatase (26 Jun 1999) |
| acetyl CoA-(beta-aminoethyl)-L-cysteine omega-N-acetyltransferase | <enzyme> Forms s-(beta-n-acetyl-aminoethyl)-l-cysteine Registry number: EC 2.3.1.- Synonym: acoac-acetyltransferase, acetyl coenzyme a-(beta-aminoethyl)-l-cysteine omega-n-acetyltransferase (26 Jun 1999) |
| acetyl CoA-deacetylcephalosporin C acetyltransferase | <enzyme> Product of cefg gene of cephalosporium acremonium; amino acid sequence has been determined Registry number: EC 2.3.1.- Synonym: acetyl coenzyme a-decatylcephalosporin c acetyltransferase, acetyl CoA-deacetylcephalosporin c o-acetyltransferase, dcpc-atf, deacetylcephalosporin c acetyltransferase, cefg gene product (26 Jun 1999) |
| acetyl methylcarbinol | <chemical> 3-hydroxy-2-butanone. A product of fermentation. It is a component of the butanediol cycle in microorganisms. In mammals it is oxidised to carbon dioxide. Chemical name: 2-Butanone, 3-hydroxy- (12 Dec 1998) |
| acetyl phosphate | CH3CO-OPO32-;a "high energy" phosphate that acts as an acetate donor in the metabolism of various bacteria. Synonym: acetic phosphoric anhydride. (05 Mar 2000) |
| acetyl reduction assay | <investigation> A technique for measuring the nitrogen fixation activity in photosynthetic organisms. It uses a flame ionisation detector and a gas chromatography apparatus to determine the reduction of acetylene to ethylene by the enzyme nitrogenase. (06 May 1997) |
| acetyl sulfisoxazole | A derivative of sulfisoxazole with the same actions and uses; an antibacterial sulfa drug. (05 Mar 2000) |
| acetyl transacylase | Enzyme transferring acetyl from acetyl-CoA to acyl carrier protein and releasing CoA to begin fatty acid synthesis. Synonym: acetyl transacylase. (05 Mar 2000) |
| acetyl value | The milligrams of KOH required to neutralise the acetic acid produced by the hydrolysis of 1 g of acetylated fat; a measure of the hydroxy acids present in glycerides; notably high in castor oil. (05 Mar 2000) |
| 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-CoA | <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) |
| acetyl-CoA - lysine N6-acetyltransferase | <enzyme> First step in catabolism of lysine by saccharomyces cerevisiae Registry number: EC 2.3.1.- Synonym: accoa lysine acetyltransferase, lysine n-6-acetyltransferase, lyc1 gene product (26 Jun 1999) |
