CerP(d18:1/24:1(15Z))
CerP(d18:1/24:1(15Z)) is a ceramide 1-phosphate belonging to the sphingolipid class of molecules. Ceramides are amides of fatty acids with long-chain di- or trihydroxy bases, the commonest in animals being sphingosine and in plants phytosphingosine. The acyl group of ceramides is generally a long-chain saturated or monounsaturated fatty acid. The most frequent fatty acids found in animal ceramides are 18:0, 24:0 and 24:1(n-9). Ceramide 1-phosphates are produced by phosphorylation of ceramide by a specific ceramide kinase. Ceramide-1-phosphate was shown to be a specific and potent inducer of arachidonic acid and prostanoid synthesis in cells through the translocation and activation of the cytoplasmic phospholipase A2.

PC(P-16:0/P-18:1(11Z))
PC(P-16:0/P-18:1(11Z)) is a phosphatidylcholine (PC or GPCho). It is a glycerophospholipid in which a phosphorylcholine moiety occupies a glycerol substitution site. As is the case with diacylglycerols, glycerophosphocholines 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. PC(P-16:0/P-18:1(11Z)), in particular, consists of one chain of plasmalogen 16:0 at the C-1 position and one chain of plasmalogen 18:1n7 at the C-2 position. The plasmalogen 16:0 moiety is derived from animal fats, liver and kidney, while the plasmalogen 18:1n7 moiety is derived from animal fats, liver and kidney. Phospholipids, are ubiquitous in nature and are key components of the lipid bilayer of cells, as well as being involved in metabolism and signaling.
PC(P-16:0/P-18:1(9Z))
PC(P-16:0/P-18:1(9Z)) is a phosphatidylcholine (PC or GPCho). It is a glycerophospholipid in which a phosphorylcholine moiety occupies a glycerol substitution site. As is the case with diacylglycerols, glycerophosphocholines 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. PC(P-16:0/P-18:1(9Z)), in particular, consists of one chain of plasmalogen 16:0 at the C-1 position and one chain of plasmalogen 18:1n9 at the C-2 position. The plasmalogen 16:0 moiety is derived from animal fats, liver and kidney, while the plasmalogen 18:1n9 moiety is derived from animal fats, liver and kidney. Phospholipids, are ubiquitous in nature and are key components of the lipid bilayer of cells, as well as being involved in metabolism and signaling.
