PE: phosphatidylethanolamine; TG: triacylglycerols; PG, phosphoglycerol; PC: phosphatidylcholine; PI: phosphatidylinositol; PS: phosphatidylserine; Cer: ceramide; PA: phosphatic acid. LM ID: Lipid MAPS identity. Identification is based on exact mass of each compound and Lipid MAPS database. The assigned IDs are for general structures and can be any of the positional isomers.
