CDP-DG(18:2(9Z,11Z)/i-12:0) is a cytidine diphosphate diacylglycerol or CDP-diacylglycerol (CDP-DG). CDP-diacylglycerol is an important branchpoint intermediate in eukaryotic phospholipid biosynthesis and could be a key regulatory molecule in phospholipid metabolism. It is a glycerophospholipid in which a cytidine diphosphate moiety occupies a glycerol substitution site. As is the case with diacylglycerols, CDP-diacylglycerols 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. CDP-DG(18:2(9Z,11Z)/i-12:0), in particular, consists of one chain of (9Z,11Z)-octadecadienoic acid at the C-1 position and one chain of isododecanoic acid at the C-2 position. Cytidine diphosphate diacylglycerols are rarely noticed in analyses of lipid compositions of tissues, as they are present is such small amounts (perhaps only 0.05\\% or so of the total phospholipids).

PS(22:6(4Z,7Z,10Z,13Z,16Z,19Z)/6 keto-PGF1alpha) is an oxidized phosphatidylserine (PS). Oxidized phosphatidylserines are glycerophospholipids in which a phosphorylserine moiety occupies a glycerol substitution site and at least one of the fatty acyl chains has undergone oxidation. As all oxidized lipids, oxidized phosphatidylserines 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, phosphatidylserines 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. PS(22:6(4Z,7Z,10Z,13Z,16Z,19Z)/6 keto-PGF1alpha), in particular, consists of one chain of one 4Z,7Z,10Z,13Z,16Z,19Z-docosahexaenoyl 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 PSs can be synthesized via three different routes. In one route, the oxidized PS is synthetized de novo following the same mechanisms as for PSs 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 PS backbone, mainly through the action of LOX (PMID: 33329396).
