Plots showing dependences of RPLC retention times of unsaturated lipids to the total numbers of carbon, with each panel showing a different lipid class (TG, SM, and PC) or degree of unsaturation (1 to 4). Within each class, slightly different retention times were observed between different C=C positional isomers and sn-position isomers (vertically lined dots)
