Glycerol-3-phosphate shuttle steps
WebGlycerol-3-phosphate shuttle generates 2 ATP for every cytosolic molecule oxidized, as FADH2 bypasses the first phosphorylation site in the electron transport chain. ... LaNoue and coworkers discovered that the efflux of aspartate from mitochondria, an essential step in the MAS, is dependent on the proton-motive force generated by the ... WebGlycerol 3-phosphate is a starting material for de novo synthesis of glycerolipids. In eukaryotes, it is first acylated on its sn -1 position by an ER- or mitochondrial membrane enzyme, glycerol-3-phosphate O-acyltransferase. A second acyl group is subsequently installed on the sn -2 position making phosphatidic acids .
