PS(16:0/18:1(9Z))
PS(16:0/18:1(9Z)) is a phosphatidylserine (PS or GPSer). It is a glycerophospholipid in which a phosphorylserine moiety occupies a glycerol substitution site. As is the case with diacylglycerols, glycerophosphoserines can have many different combinations of fatty acids of varying lengths and saturation attached at the C-1 and C-2 positions. Fatty acids containing 16, 18 and 20 carbons are the most common. PS(16:0/18:1(9Z)), in particular, consists of one chain of palmitic acid at the C-1 position and one chain of oleic acid at the C-2 position. The palmitic acid moiety is derived from fish oils, milk fats, vegetable oils and animal fats, while the oleic acid moiety is derived from vegetable oils, especially olive and canola oil. Phosphatidylserine or 1,2-diacyl-sn-glycero-3-phospho-L-serine is distributed widely among animals, plants and microorganisms. It is usually less than 10\\% of the total phospholipids, the greatest concentration being in myelin from brain tissue. However, it may comprise 10 to 20 mol\\% of the total phospholipid in the plasma membrane and endoplasmic reticulum of the cell. Phosphatidylserine is an acidic (anionic) phospholipid with three ionizable groups, i.e. the phosphate moiety, the amino group and the carboxyl function. As with other acidic lipids, it exists in nature in salt form, but it has a high propensity to chelate to 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, especially during bone formation for example. As phosphatidylserine is located entirely on the inner monolayer surface of the plasma membrane (and of other cellular membranes) and it is the most abundant anionic phospholipids. Therefore phosphatidylseriine may make the largest contribution to interfacial effects in membranes involving non-specific electrostatic interactions. This normal distribution is disturbed during platelet activation and cellular apoptosis. In human plasma, 1-stearoyl-2-oleoyl and 1-stearoyl-2-arachidonoyl species predominate, but in brain (especially grey matter), retina and many other tissues 1-stearoyl-2-docosahexaenoyl species are very abundant. Indeed, the ratio of n-3 to n-6 fatty acids in brain phosphatidylserine is very much higher than in most other lipids. 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 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. PS(16:0/18:1(9Z)) is a phosphatidylserine.

PC(14:1(9Z)/18:1(12Z)-2OH(9,10))
PC(14:1(9Z)/18:1(12Z)-2OH(9,10)) is an oxidized phosphatidylcholine (PC or GPCho). Oxidized phosphatidylcholines are glycerophospholipids in which a phosphorylcholine moiety occupies a glycerol substitution site and at least one of the fatty acyl chains has undergone oxidation. As all oxidized lipids, oxidized phosphatidylcholines 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, glycerophosphocholines 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. PC(14:1(9Z)/18:1(12Z)-2OH(9,10)), in particular, consists of one chain of one 9Z-tetradecenoyl at the C-1 position and one chain of 9,10-hydroxy-octadecenoyl 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 PCs can be synthesized via three different routes. In one route, the oxidized PC is synthetized de novo following the same mechanisms as for PCs but incorporating oxidized acyl chains (PMID: 33329396). An alternative is the transacylation of one of the non-oxidated acyl chains with an oxidated acylCoA (PMID: 33329396). The third pathway results from the oxidation of the acyl chain while still attached to the PC backbone, mainely through the action of LOX (PMID: 33329396).
PC(18:1(12Z)-2OH(9,10)/14:1(9Z))
PC(18:1(12Z)-2OH(9,10)/14:1(9Z)) is an oxidized phosphatidylcholine (PC or GPCho). Oxidized phosphatidylcholines are glycerophospholipids in which a phosphorylcholine moiety occupies a glycerol substitution site and at least one of the fatty acyl chains has undergone oxidation. As all oxidized lipids, oxidized phosphatidylcholines 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, glycerophosphocholines 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. PC(18:1(12Z)-2OH(9,10)/14:1(9Z)), in particular, consists of one chain of one 9,10-hydroxy-octadecenoyl at the C-1 position and one chain of 9Z-tetradecenoyl 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 PCs can be synthesized via three different routes. In one route, the oxidized PC is synthetized de novo following the same mechanisms as for PCs but incorporating oxidized acyl chains (PMID: 33329396). An alternative is the transacylation of one of the non-oxidated acyl chains with an oxidated acylCoA (PMID: 33329396). The third pathway results from the oxidation of the acyl chain while still attached to the PC backbone, mainely through the action of LOX (PMID: 33329396).
