Metabolite Identification
Common NamePGP(14:0/20:0)
DescriptionPGP(14:0/20:0) belongs to the class of glycerophosphoglycerophosphates, also called phosphatidylglycerophosphates (PGPs). These lipids contain a common glycerophosphate skeleton linked to at least one fatty acyl chain and a glycero-3-phosphate moiety. As is the case with diacylglycerols, phosphatidylglycerophosphates can have many different combinations of fatty acids of varying lengths and saturation attached to the C-1 and C-2 positions. PGP(14:0/20:0), in particular, consists of one tetradecanoyl chain to the C-1 atom, and one eicosanoyl to the C-2 atom. In E. coli, PGPs can be found in the cytoplasmic membrane. The are synthesized by the addition of glycerol 3-phosphate to a CDP-diacylglycerol. In turn, PGPs are dephosphorylated to Phosphatidylglycerols (PGs) by the enzyme Phosphatidylglycerophosphatase.
