| 1-acylglycerophosphocholine o-acyltransferase | <enzyme> An enzyme localised predominantly within the plasma membrane of lymphocytes. It catalyses the transfer of long-chain fatty acids, preferentially unsaturated fatty acids, to lysophosphatides with the formation of 1,2-diacylglycero-3-phosphocholine and CoA. Chemical name: Acyl-CoA:1-acyl-sn-glycero-3-phosphocholine O-acyltransferase Registry number: EC 2.3.1.23 (12 Dec 1998) |

| 1-acyl-glycerophosphoethanolamine acyltransferase | <enzyme> Guinea pig heart microsome enzyme; not the same as EC 2.3.1.25 (plasmalogen synthase) Registry number: EC 2.3.1.- Synonym: acyl-CoA-1-acylglycerophosphoethanolamine 2-acyltransferase, 1-agpe acyltransferase, acyl-coenzyme a-1-acylglycerophosphoethanolamine 2-acyltransferase (26 Jun 1999) |
| lecithin acyltransferase | <enzyme> An enzyme that reversibly transfers an acyl residue from a lecithin to cholesterol, forming a 1-acylglycerophosphocholine (a lysolecithin) and a cholesterol ester; a deficiency of this enzyme leads to an accumulation of unesterified cholesterol in plasma resulting in anaemia, proteinuria, renal failure, and corneal opacities; LCAT is also low in individuals with fish-eye disease. Synonym: lecithin acyltransferase. Acronym: LCAT (05 Mar 2000) |
| lecithin acyltransferase deficiency | A disease characterised by deficiency or low levels of plasma lecithin cholesterol acyl transferase. Clinical manifestations include corneal opacity, anaemia, and proteinuria. (12 Dec 1998) |
| lecithin-cholesterol acyltransferase | <enzyme> An enzyme that reversibly transfers an acyl residue from a lecithin to cholesterol, forming a 1-acylglycerophosphocholine (a lysolecithin) and a cholesterol ester; a deficiency of this enzyme leads to an accumulation of unesterified cholesterol in plasma resulting in anaemia, proteinuria, renal failure, and corneal opacities; LCAT is also low in individuals with fish-eye disease. Synonym: lecithin acyltransferase. Acronym: LCAT (05 Mar 2000) |
| lecithin-retinol acyltransferase | <enzyme> Transfers 1-acyl moiety from lecithin to retinol-cellular retinol-binding protein, type II, to produce retinyl esters; does not use CoA Registry number: EC 2.3.1.- (26 Jun 1999) |
| long-chain-alcohol O-fatty-acyltransferase | <enzyme> Catalyses the final step in biosynthesizing storage liquid waxes from long chain fatty acyl CoA and fatty alcohols; forming predominantly c42 wax esters Registry number: EC 2.3.1.75 Synonym: acyl-coenzyme a-alcohol transacylase, aca transacylase, acyl-CoA-alcohol transacylase, wax-ester synthase (26 Jun 1999) |
| lysolecithin-lecithin acyltransferase | <enzyme> An enzyme that catalyses the reversible reaction of lysolecithin and another phospholipid (e.g., phosphatidylethanolamine) to form lecithin and lysophosphatidylethanolamine; a major route in the restructuring of lecithin. (05 Mar 2000) |
| lysomonogalactosyldiacylglycerol acyltransferase | <enzyme> Transfers acyl group from acyl-acyl-carrier protein to an endogenous lysomonogalactosyldiacylglycerol to form monogalactosyldiacylglycerol Registry number: EC 2.3.1.- Synonym: acp-lysomgdg acyltransferase, monogalactosyldiacylglycerol synthase, mgdg synthase (26 Jun 1999) |
| lysophosphatidic acid acyltransferase | 1-acylglycerol-3-phosphate acyltransferase. (05 Mar 2000) |
| 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) |
| acidulated phosphate fluoride | <chemical> Phosphoric acid, mixt. With sodium fluoride (naf). A sodium fluoride solution, paste or powder, which has been acidulated to pH 3 to 4 and buffered with a phosphate. It is used in the prevention of dental caries. Pharmacological action: fluorides, topical. Chemical name: Phosphoric acid, mixt. With sodium fluoride (NaF) (12 Dec 1998) |
| acyl dihydroxyacetone phosphate oxidoreductase | <enzyme> Forms acyl-sn-glycerol 3-phosphate; uses NADPH Registry number: EC 1.1.1.- (26 Jun 1999) |
| adenosine 3',5'-cyclic phosphate phosphodiesterase | <enzyme> An enzyme that catalyses the hydrolysis of adenosine 3',5'-cyclic phosphate forming 5'-AMP. A crucial step in the regulation of cellular adenosine 3',5'-cyclic phosphate levels. Inhibited by caffeine. Synonym: cAMP phosphodiesterase. (05 Mar 2000) |
| adenosine 3'-phosphate | 3'-Adenylic acid. See: adenylic acid. (05 Mar 2000) |
