| glycerogelatin | A preparation made of equal parts of gelatin and glycerin; a firm mass liquefying at gentle heat; it is used as a vehicle for suppositories and urethral bougies. Synonym: glycerin jelly, glycerogelatin, glycogelatin. (05 Mar 2000) |
|---|---|
| glyceroketone | An obsolete term for dihydroxyacetone. (05 Mar 2000) |
| glycerokinase | <enzyme> An enzyme that catalyses the formation of glycerol 3-phosphate from ATP and glycerol. Dihydroxyacetone and l-glyceraldehyde can also act as acceptors; utp and, in the case of the yeast enzyme, itp and GTP can act as donors. It provides a way for glycerol derived from fats or glycerides to enter the glycolytic pathway. Chemical name: ATP:glycerol 3-phosphotransferase Registry number: EC 2.7.1.30 (12 Dec 1998) |
| glycerol | <biochemistry> A metabolic intermediate, but primarily of interest as the central structural component of the major classes of biological lipids, triglycerides and phosphatidyl phospholipids. Also used as a cryoprotectant. (18 Nov 1997) |
| glycerol dehydratase | <enzyme> Requires a cobamide coenzyme Registry number: EC 4.2.1.30 (26 Jun 1999) |
| glycerol kinase | <enzyme> An enzyme that catalyses the formation of glycerol 3-phosphate from ATP and glycerol. Dihydroxyacetone and l-glyceraldehyde can also act as acceptors; utp and, in the case of the yeast enzyme, itp and GTP can act as donors. It provides a way for glycerol derived from fats or glycerides to enter the glycolytic pathway. Chemical name: ATP:glycerol 3-phosphotransferase Registry number: EC 2.7.1.30 (12 Dec 1998) |
| glycerol oxidase | <enzyme> Oxidises glycerol in the presence of oxygen to glyceraldehyde and hydrogen peroxide without the requirement of any exogenous cofactors; protoheme ix and copper are in prosthetic group Registry number: EC 1.1.3.- (26 Jun 1999) |
| glycerol phosphate | The anion of a phosphoric ester of glycerol; the 3-derivative is the central component of phosphatidates (R-glycerol 3-phosphate). Synonym: glycerophosphate. (05 Mar 2000) |
| glycerol-1-phosphate dehydrogenase | <enzyme> From the archaebacterium methanobacterium thermoautotrophicum; forms the glycerophosphate which is the mirror image of that found in eubacterial and eukaryotic ether phospholipids Registry number: EC 1.1.1.- Synonym: sn-glycerol-1-phosphate - nad+ oxidoreductase, sn-g-1-p dehydrogenase (26 Jun 1999) |
| glycerol-3-phosphate - glucose phosphotransferase | <enzyme> Catalyses the formation of glycerol and glucose-6-phosphate Registry number: EC 2.7.1.142 Synonym: gro3p-glucose transphorylase, glycerol 3-phosphate-glucose transphorylase (26 Jun 1999) |
| glycerol-3-phosphate acyltransferase | <enzyme> An enzyme that participates in phospholipid biosynthesis, catalyzing the transfer of an acyl group from a fatty acyl-CoA to sn-glycerol-3-phosphate producing coenzyme A and lysophosphatidic acid. (05 Mar 2000) |
| glycerol-3-phosphate dehydrogenase | Alpha-Glycerol phosphate dehydrogenase; 3-phosphoglycerol dehydrogenase;an oxidoreductase that catalyses the interconversion of dihydroxyacetone phosphate and sn-glycerol 3-phosphate, with the participation of NAD+; its action provides the glycerol moiety from carbohydrate during lipogenesis. (05 Mar 2000) |
| glycerol-3-phosphate o-acyltransferase | <enzyme> An enzyme that transfers acyl groups from acyl-CoA to glycerol-3-phosphate to form monoglyceride phosphates. It acts only with CoA derivatives of fatty acids of chain length above c-10. Also forms diglyceride phosphates. Chemical name: Acyl-CoA:sn-glycerol-3-phosphate 1-O-acyltransferase Registry number: EC 2.3.1.15 (12 Dec 1998) |
| glycerolphosphate dehydrogenase | <enzyme> Registry number: EC 1.1.- (12 Dec 1998) |
| glycerone | <chemical> 1,3-dihydroxy-2-propanone. A ketotriose compound. Its addition to blood preservation solutions results in better maintenance of 2,3-diphosphoglycerate levels during storage. It is readily phosphorylated to dihydroxyacetone phosphate by triokinase in erythrocytes. In combination with naphthoquinones it acts as a sunscreening agent. Chemical name: 2-Propanone, 1,3-dihydroxy- (12 Dec 1998) |
