PS(18:4(6Z,9Z,12Z,15Z)/18:4(6Z,9Z,12Z,15Z))
PS(18:4(6Z,9Z,12Z,15Z)/18:4(6Z,9Z,12Z,15Z)) is a phosphatidylserine. It is a glycerophospholipid in which a phosphorylserine moiety occupies a glycerol substitution site. As is the case with diacylglycerols, phosphatidylserines can have many different combinations of fatty acids of varying lengths and saturation attached to the C-1 and C-2 positions. PS(18:4(6Z,9Z,12Z,15Z)/18:4(6Z,9Z,12Z,15Z)), in particular, consists of one chain of stearidonic acid at the C-1 position and one chain of stearidonic acid at the C-2 position. Phosphatidylserine or 1,2-diacyl-sn-glycero-3-phospho-L-serine is distributed widely among animals, plants, and microorganisms. Phosphatidylserine is an acidic (anionic) phospholipid with three ionizable groups (i.e. the phosphate moiety, the amino group and the carboxyl group). As with other acidic lipids, it exists in nature in salt form, but it has a high propensity to chelate calcium via the charged oxygen atoms of both the carboxyl and phosphate moieties, modifying the conformation of the polar head group. This interaction may be of considerable relevance to the biological function of phosphatidylserine. While most phospholipids have a saturated fatty acid on C-1 and an unsaturated fatty acid on C-2 of the glycerol backbone, the fatty acid distribution at the C-1 and C-2 positions of glycerol within phospholipids is continually in flux, owing to phospholipid degradation and the continuous phospholipid remodeling that occurs while these molecules are in membranes. Phosphatidylserines typically carry a net charge of -1 at physiological pH. They mostly have a palmitic or stearic acid on carbon 1 and a long chain unsaturated fatty acid (e.g. 18:2, 20:4 and 22:6) on carbon 2. PS biosynthesis involves an exchange reaction of serine for ethanolamine in PE.
PE(14:1(9Z)/6 keto-PGF1alpha)
PE(14:1(9Z)/6 keto-PGF1alpha) is an oxidized phosphatidylethanolamine (PE). Oxidized phosphatidylethanolamines are glycerophospholipids in which a phosphorylethanolamine moiety occupies a glycerol substitution site and at least one of the fatty acyl chains has undergone oxidation. As all oxidized lipids, oxidized phosphatidylethanolamines belong to a group of biomolecules that have a role as signaling molecules. The biosynthesis of oxidized lipids is mediated by several enzymatic families, including cyclooxygenases (COX), lipoxygenases (LOX) and cytochrome P450s (CYP). Non-enzymatically oxidized lipids are produced by uncontrolled oxidation through free radicals and are considered harmful to human health (PMID: 33329396). As is the case with diacylglycerols, phosphatidylethanolamines can have many different combinations of fatty acids of varying lengths, saturation and degrees of oxidation attached at the C-1 and C-2 positions. PE(14:1(9Z)/6 keto-PGF1alpha), in particular, consists of one chain of one 9Z-tetradecenoyl at the C-1 position and one chain of 6-Keto-prostaglandin F1alpha at the C-2 position. Phospholipids are ubiquitous in nature and are key components of the lipid bilayer of cells, as well as being involved in metabolism and signaling. Similarly to what occurs with phospholipids, the fatty acid distribution at the C-1 and C-2 positions of glycerol within oxidized phospholipids is continually in flux, owing to phospholipid degradation and the continuous phospholipid remodeling that occurs while these molecules are in membranes. Oxidized PEs can be synthesized via three different routes. In one route, the oxidized PE is synthetized de novo following the same mechanisms as for PEs but incorporating oxidized acyl chains (PMID: 33329396). An alternative is the transacylation of one of the non-oxidized acyl chains with an oxidized acylCoA (PMID: 33329396). The third pathway results from the oxidation of the acyl chain while still attached to the PE backbone, mainly through the action of LOX (PMID: 33329396).
