sn-Glycerol 3-phosphate [a] [b] is the organic ion with the formula HOCH 2 CH(OH)CH 2 OPO 3 2-. It is one of two stereoisomers of the ester of dibasic phosphoric acid (HOPO 3 2- ) and glycerol . It is a component of bacterial and eukaryotic glycerophospholipids . [ 2 ]
In the cytosol of the cell (for example a muscle cell), the glycerol will be converted to glyceraldehyde 3-phosphate, which is an intermediate in the glycolysis, to get further oxidized and produce energy. However, the main steps of fatty acids catabolism occur in the mitochondria. [16]
The glycerol also enters the bloodstream and is absorbed by the liver or kidney where it is converted to glycerol 3-phosphate by the enzyme glycerol kinase. Hepatic glycerol 3-phosphate is converted mostly into dihydroxyacetonephosphate (DHAP) and then glyceraldehyde 3-phosphate (GA3P) to rejoin the glycolysis and gluconeogenesis pathway. [15]
Thus, the two substrates of this enzyme are sn-glycerol 3-phosphate and D-glucose, whereas its two products are glycerol and D-glucose 6-phosphate. This enzyme belongs to the family of transferases , specifically those transferring phosphorus-containing groups ( phosphotransferases ) with an alcohol group as acceptor.
Triglycerides are built from three fatty acids, esterified onto each of three hydroxy groups of glycerol, which is derived from glycerol 3-phosphate.In mammals, glycerol 3-phosphate is usually synthesized through glycolysis, a metabolic pathway that degrades glucose into fructose 1,6-bisphosphate and then into two molecules of dihydroxyacetone phosphate, which beget glycerol 3-phosphate and ...

1-acyl-sn-glycerol-3-phosphate acyltransferase gamma is an enzyme that in humans is encoded by the AGPAT3 gene. [5]The protein encoded by this gene is an acyltransferase (specifically, 1-acylglycerol-3-phosphate O-acyltransferase) that converts lysophosphatidic acid (1-acyl-sn-glycerol 3-phosphate) into phosphatidic acid, which is the second step in the de novo phospholipid biosynthetic pathway.
The 3 substrates of this enzyme are ATP, H 2 O, and glycerol-3-phosphate, whereas its 3 products are ADP, phosphate, and glycerol-3-phosphate. This enzyme belongs to the family of hydrolases , specifically those acting on acid anhydrides to catalyse transmembrane movement of substances.
