Dhap to glycerol 3-phosphate

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. WebMar 6, 2024 · The enzyme glycerol-3-phosphate dehydrogenase reversibly converts glycerol-3- phosphate into DHAP (Figure 6.22). This reaction, which is an oxidation, transfers electrons to NAD+ to produce NADH. In the reverse reaction, production of glycerol-3- phosphate from DHAP, of course, requires electrons from NADH for the …
