Two phosphonolipids (ceramide 2-aminoethylphosphonates), CAEPn-1 and CAEPn-2, were isolated from the hepatopancreas of the Giant Ezo scallop Patinopecten yessoensis (Phylum, Mollusca; Class, Bivalvia; Family, Pectinidae). Their chemical structures were completely characterized by TLC-immunostaining assay, aliphatic analyses, infrared analysis and matrix assisted laser desorption ionization time-of-flight mass spectrometry. The major fatty acids were 16:0, br17:0 17:0 and 18:0 for CAEPn-1, and their 2-hydroxylated acids for CAEPn-2. The major sphingoids were d16:1, d17:1, d18:1, d18:2, d18:3 and d19:3 for CAEPn-1, and d18:3 and d19:3 for CAEPn-2.
