Comparison of non-polar parts of GPL and DAGE. (A) Profiles (% of lipid class) of 1-O-alkyl-2-acyl parts of glycerophospholipid (GPL) and diacylglycerol ether (DAGE) molecular species in the soft coral Paragorgia arborea. (B) A dendrogram of cluster analysis of 6 samples of DAGE and 12 samples of four GPL classes by their 1-O-alkyl-2-acyl part composition. Ethanolamine, choline, inositol and serine GPL are abbreviated as PE, PC, PI, and PS, respectively; alkyl/acyl and diacyl forms, as Xa/Y and X/Y; Xa, alkyl group; X and Y, acyl groups (number of carbon atoms: number of double bonds). 16:0ap/20:4 is the sum of plasmanyl and plasmenyl forms.
