NMR spectra of 15 reference lipid standards used to train the MLP for lipid quantification, with the name of the standard listed on the left and the lipid groups quantified on the right. The ‘**’ symbol indicates that there are small amounts of unknown lipids in the SM. Abbreviations: DHA = docosahexaenoic acid; EC = esterified cholesterol; FC = free cholesterol; LA = linoleic acid; LPC = lysophosphatidylcholine; MUFA = monounsaturated fatty acids; Om3 = omega-3 fatty acids; Om6 = omega-6 fatty acids; Om9 = omega-9 fatty acids; PC = phosphatidylcholine; PE = phosphatidylethanolamine; PUFA = polyunsaturated fatty acids; SFA = saturated fatty acids; SM = sphingomyelin; TC = total cholesterol; TFA = total fatty acids; Tg = total triglycerides; TPL = total phospholipids.
