This species is an important intermediate in the synthesis of many phosphoglycerides. The presence of an additional group attached to the phosphate allows for many different phosphoglycerides. By convention, structures of these compounds show the 3 glycerol carbon atoms vertically with the phosphate attached to carbon atom number three (at the ...
Glycerol 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 .
Phosphatidylglycerol is a glycerophospholipid found in pulmonary surfactant [1] and in the plasma membrane where it directly activates lipid-gated ion channels. The general structure of phosphatidylglycerol consists of a L-glycerol 3-phosphate backbone ester-bonded to either saturated or unsaturated fatty acids on carbons 1 and 2.
Glyceroneogenesis is a metabolic pathway which synthesizes glycerol 3-phosphate (used to form triglycerides) from precursors other than glucose. [1] Usually, glycerol 3-phosphate is generated from glucose by glycolysis, in the liquid of the cell's cytoplasm (the cytosol).
In contrast, conventional glycerophospholipids and triglycerides are triesters. [1] Structural types include: Ether phospholipids: phospholipids are known to have ether-linked "tails" instead of the usual ester linkage. [1] Ether on sn-1, ester on sn-2: "ether lipids" in the context of bacteria and eukaryotes refer to this class of lipids.
Besides de novo synthesis, PA can be formed in three ways: By phospholipase D (PLD), via the hydrolysis of the P-O bond of phosphatidylcholine (PC) to produce PA and choline. [4] By the phosphorylation of diacylglycerol (DAG) by DAG kinase (DAGK). By the acylation of lysophosphatidic acid by lysoPA-acyltransferase (LPAAT); this is the most ...
Glycerol kinase, encoded by the gene GK, is a phosphotransferase enzyme involved in triglycerides and glycerophospholipids synthesis. Glycerol kinase catalyzes the transfer of a phosphate from ATP to glycerol thus forming glycerol 3-phosphate: ATP + glycerol <=> ADP + sn-glycerol 3-phosphate
In enzymology, a glycerol-3-phosphate O-acyltransferase (EC 2.3.1.15) is an enzyme that catalyzes the chemical reaction. acyl-CoA + sn-glycerol 3-phosphate CoA + 1-acyl-sn-glycerol 3-phosphate
