Molecular structures of five representative plant sphingolipid classes (Nomenclature from LIPID MAPS45). (a) A free long chain base, LCB(t18:1(8E)); (b) A ceramide (Cer), Cer(t18:1(8E)/24:0-OH(R)); (c) A monoglycosylceramide (MonoGlcCer), GluCer(t18:1(8E)/24:0-OH(R)); (d) A GIPC, GluN-GluA-IPC(t18:1(8E)/24:0-OH(R)). (e) A trihexosylceramide (TriHexCer), Man-Man-Glu-Cer(t18:1(8E)/24:0-OH(R)).
