| 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.

| 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 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) |
| 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) |
| pentose phosphate cycle | <biochemistry> A pathway of hexose oxidation in which glucose-6-phosphate undergoes two successive oxidations by NADP, the final one being an oxidative decarboxylation to form a pentose phosphate. Diverges from this when glucose-6-phosphate is oxidized to ribose 5 phosphate by the enzyme glucose-6 phosphate dehydrogenase. This step reduces NADP to NADPH, generating a source of reducing power in cells for use in reductive biosyntheses. In plants, part of the pathway functions in the formation of hexoses from carbon dioxide in photosynthesis. Also important as source of pentoses, for example for nucleic acid biosynthesis. This pathway is the main metabolic pathway in neutrophils, congenital deficiency in the pathway produces sensitivity to infection. Alternative metabolic route to Embden Meyerhof pathway for breakdown of glucose. (18 Nov 1997) |
