| magnesium peroxide | Decomposes in water to hydrogen peroxide; used as an ingredient in dentifrices and in antiseptic dusting powder. (05 Mar 2000) |
| medicinal zinc peroxide | A mixture of zinc peroxide, zinc carbonate, and zinc hydroxide; a topical disinfectant, astringent, and deodorant. (05 Mar 2000) |
| peroxide | <chemistry> An oxide containing more oxygen than some other oxide of the same element. Formerly peroxides were regarded as the highest oxides. Cf. Per-. Source: Websters Dictionary (01 Mar 1998) |
| hydrogen peroxide | <chemical> Hydrogen peroxide is produced by vertebrate phagocytes and is used in bacterial killing (the myeloperoxidase halide system). (05 May 1997) |
| sodium peroxide | Na2O2;used externally as a paste or soap in the treatment of comedones and acne. (05 Mar 2000) |
| zinc peroxide | ZnO2;a yellowish white powder, insoluble in water and decomposed by acids; used in pharmaceutical preparations. Synonym: zinc superoxide. (05 Mar 2000) |
| urea peroxide | CH4N2O-H2O2;a white crystalline compound used in an aqueous solution as an oxidizing mouthwash. (05 Mar 2000) |
| 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-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-1-alkyl-2-lyso-sn-glycero-3-phosphocholine acetyltransferase | <enzyme> Transfers acetate from acetyl CoA to the sn-2-position of 1-alkyl-2-lyso-glycerophosphocholine, forming the substrate for 1-alkylglycerophosphocholine acetyltransferase (EC 2.3.1.67) Registry number: EC 2.3.1.- Synonym: acopc acetyltransferase, 1-alkyl-2-lyso-sn-glycero-3-phosphocholine-acetyl CoA acetyltransferase, alkyllyso-gp-acetyl-CoA acetyltransferase, acetyl-coenzyme a-1-alkyl-2-lyso-sn-glycero-3-phosphocholine acetyltransferase (26 Jun 1999) |
| acetyl-CoA acetyltransferase | An acetyltransferase forming acetoacetyl-CoA from two molecules of acetyl-CoA, releasing one CoA. A key step in ketogenesis and sterol synthesis. Synonym: acetoacetyl-CoA thiolase, acetyl-CoA thiolase, thiolase. (05 Mar 2000) |
| acetyl-CoA acylase | <enzyme> An enzyme that catalyses reversibly the hydrolysis of acetyl-CoA to yield CoA and acetate. The enzyme is involved in the oxidation of fatty acids. Chemical name: Acetyl-CoA hydrolase Registry number: EC 3.1.2.1 (12 Dec 1998) |
