Chemical name: L-Glutamine:D-fructose-6-phosphate aminotransferase (hexose-isomerizing) Registry number: EC 2.6.1.16 (12 Dec 1998) |
| glyceraldehdye 3 phosphate | <biochemistry> Three carbon intermediate of the glycolytic pathway formed by the cleavage of fructose 1,6 bisphosphate, catalysed by the enzyme aldolase. Also involved in reversible interchange between glycolysis and the pentose phosphate pathway. (18 Nov 1997) |
| glyceraldehyde 3-phosphate | <biochemistry> In glycolysis, glyceraldehyde 3-phosphate is created from dihydroxyacetone phosphate with the aid of triose-phosphate isomerase. In turn, it an dorganic phosphate and NAD+ are converted into 1,3-bisphosphoglycerate, NADH and free hydrogen with the aid of glyceraldehyde 3-phosphate dehydrogenase. (09 Oct 1997) |
| glyceraldehyde 3-phosphate dehydrogenase | <biochemistry> In glycolysis, this enzyme catalyses the conversion of glyceraldehyde 3-phosphate and organic phosphate and NAD+ into 1,3-bisphosphoglycerate and NADH and free hydrogens (and viceversa) by transferring hydrogens and electrons between the molecules. (09 Oct 1997) |

| 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 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 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) |
