WebGlycerol is one of the most important substrates involved in phospholipid biosynthesis, along with dihydroxyacetone phosphate (DHAP) as an intermediate of glycolysis. Organisms produce glycerol 3-phosphate (G3P) from endogenous DHAP and/or exogenous glycerol to synthesize glycerophospholipids from G3P. WebMar 6, 2024 · 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 reduction.
