Dhap to glycerol-3-phosphate
The glycerol-3-phosphate shuttle is a mechanism that regenerates NAD+ from NADH, a by-product of glycolysis. The shuttle consists of the sequential activity of two proteins: GPD1 which transfers an electron pair from NADH to dihydroxyacetone phosphate (DHAP), forming glycerol-3-phosphate (G3P) and … See more The glycerol phosphate shuttle was first characterized as a major route of mitochondrial hydride transport in the flight muscles of blow flies. It was initially believed that the system would be inactive in mammals due to … See more • Malate-aspartate shuttle • Mitochondrial shuttle See more • See more In this shuttle, the enzyme called cytoplasmic glycerol-3-phosphate dehydrogenase 1 (GPD1 or cGPD) converts dihydroxyacetone phosphate (2) to glycerol 3-phosphate (1) … See more WebNov 2, 2024 · Figure 5.4: Glycerol as a substrate for gluconeogenesis; after phosphorylation to glycerol 3-phosphate it can be converted to DHAP, which can enter …

WebFeb 24, 2014 · Glycerol 3-phosphate is an intermediate common to both lipid and carbohydrate metabolism. Its oxidation to dihydroxyacetone phosphate (DHAP) by mGPDH and the subsequent reduction of DHAP back to glycerol 3-phosphate by a distinct soluble GPDH (cytosolic GPDH; cGPDH; EC 1.1.1.8; gene symbol GPD1) regenerates NAD + … WebGlycerol enters the liver and is converted to glycerol-3-P by glycerol kinase, which is then oxidized to DHAP by glycerol-3-phosphate dehydrogenase. The labeled glycerol-3-P is in rapid equilibrium with …
