PG(a-13:0/18:2(9Z,11Z))

[(2S)-2,3-dihydroxypropoxy][(2R)-3-[(10-methyldodecanoyl)oxy]-2-[(9Z,11Z)-octadeca-9,11-dienoyloxy]propoxy]phosphinic acid

C37H69O10P (704.4628104)

PG(a-13:0/18:2(9Z,11Z)) is a phosphatidylglycerol - a glycerophospholipid in which a phosphoglycerol moiety occupies a glycerol substitution site. As is the case with diacylglycerols, phosphatidylglycerols 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. PG(a-13:0/18:2(9Z,11Z)), in particular, consists of one chain of anteisotridecanoic acid at the C-1 position and one chain of (9Z,11Z)-octadecadienoic acid at the C-2 position. Phosphatidylglycerol is present at a level of 1-2\\% in most animal tissues, but it can be the second most abundant phospholipid in lung surfactant (up to 11\\% of the total). It is well established that the concentration of phosphatidylglycerol increases during fetal development. Phosphatidylglycerol may be present in animal tissues merely as a precursor for cardiolipin synthesis.

PA(16:1(9Z)/18:1(12Z)-2OH(9,10))

[(2R)-2-{[(9S,10S,12Z)-9,10-dihydroxyoctadec-12-enoyl]oxy}-3-[(9Z)-hexadec-9-enoyloxy]propoxy]phosphonic acid

C37H69O10P (704.4628104)

PA(16:1(9Z)/18:1(12Z)-2OH(9,10)) is an oxidized phosphatidic acid (PA). Oxidized phosphatidic acids are glycerophospholipids in which a phosphate moiety occupies a glycerol substitution site and at least one of the fatty acyl chains has undergone oxidation. As all oxidized lipids, oxidized phosphatidic acids 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, phosphatidic acids 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. PA(16:1(9Z)/18:1(12Z)-2OH(9,10)), in particular, consists of one chain of one 9Z-hexadecenoyl 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 PAs can be synthesized via three different routes. In one route, the oxidized PA is synthetized de novo following the same mechanisms as for PAs 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 PA backbone, mainly through the action of LOX (PMID: 33329396).
