Ceramide 2-aminoethylphosphonate (CAEPn) was found to be the principal phosphosphingolipidsin the phylum Mollusca, Cnidaria (Coelenterata) and Protozoa. The presenceof CAEPn as a major phospholipid constituent in these organisms is unique, since it hasnot been found, or is present only in trace amounts in other animals investigated so far.In this paper, we describe the isolation and the structural characterization of CAEPn fromthe umbrella portion of the jellyfish, Stomolophus nomurai (Echizen-kurage) (phylumCnidaria, class Scyphozoa). The chemical structure was completely characterized by TLC-immunostaining assay, aliphatic analyses, infrared analysis and matrix-assisted laserdesorption ionization time-of-flight mass spectrometry. The ceramide moiety of purifiedCAEPn consisted primarily of miristic and palmitic acids, and the sole octadecasphingadienine.
