Description
sn-Glycerol-3-phosphate (G3P) is a phosphoric ester of glycerol that is a chemical intermediate in glycolysis and lipid metabolism.1 G3P is an integral part of the glycerophosphate shuttle, in which NADH is oxidized to regenerate NAD+ and reducing equivalents are transferred to the oxidative phosphorylation pathway.2,3,4,5 G3P is used as a substrate for lipid biosynthesis pathways in synthetic biology, in studies of reactive oxygen species in heart tissue, and to measure phosphatidic acid in cell cultures.6,7,8 It plays a vital role in systemic acquired resistance in plant immunity.9 G3P availability affects insulin production as a substrate for glycerol-3-phosphate phosphatase.10 Altered levels of G3P have been found in the saliva of Alzheimer's, frontal lobe dementia, and Lewy body disease patients.11WARNING This product is not for human or veterinary use.
