Glycerophospholipids are derived from glycerol-3-phosphate in a de novo pathway. [3] The term glycerophospholipid signifies any derivative of glycerophosphoric acid that contains at least one O-acyl, or O-alkyl, or O-alk-1'-enyl residue attached to the glycerol moiety. [4] The phosphate group forms an ester linkage to the glycerol.
Example of an ethanolamine plasmalogen with the characteristic vinyl ether linkage at the sn-1 position and an ester linkage at the sn-2 position. Plasmalogens are a class of glycerophospholipid with a plasmenyl group linked to a lipid at the sn-1 position of the glycerol backbone.
Examples of glycerophospholipids found in biological membranes are phosphatidylcholine (also known as PC, GPCho or lecithin), phosphatidylethanolamine (PE or GPEtn) and phosphatidylserine (PS or GPSer).
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.
Glycerophospholipids have three components: fatty acid lipid groups (orange), glycerol backbone (white), and 3-phosphate ester (green) Glycerol 3-phosphate is a starting material for de novo synthesis of glycerolipids.
glycerophospholipid — these fats are major building blocks of cell membranes, changes in whose levels appear to be linked to diabetes branched-chain amino acid (BCAA) — essential amino acids ...
Phosphatidylserine is a phospholipid—more specifically a glycerophospholipid—which consists of two fatty acids attached in ester linkage to the first and second carbon of glycerol and serine attached through a phosphodiester linkage to the third carbon of the glycerol.
The primary saponifiable lipids are free fatty acids, neutral glycerolipids, glycerophospholipids, sphingolipids, and glycolipids. [ 1 ] By comparison, the non-saponifiable class of lipids is made up of terpenes, including fat-soluble A and E vitamins, and certain steroids, such as cholesterol.
