WebApr 28, 2024 · Glyceraldehyde-3-phosphate dehydrogenase (GAPDH) is a highly conserved enzyme within the glycolytic pathway. GAPDH catalyzes the transformation of glyceraldehyde 3-phosphate to glycerate-1, 3-biphosphate, a process accompanied by the production of NADH. Its role in the NADPH production system of the oleaginous … WebThe DHAP is isomerized (through redox) by glycerol 3-P dehydrogenase in the cytoplasm which uses cytosolic NADH.

Another … WebGlycerol 3-phosphate is synthesized by reducing dihydroxyacetone phosphate (DHAP), a glycolysis intermediate, with glycerol-3-phosphate dehydrogenase. DHAP and thus glycerol 3-phosphate is also possible to be synthesized from amino acids and citric acid cycle intermediates via glyceroneogenesis pathway.
