    Notes: -A ganglioside molecular species [LLG-3 (1)] has been obtained from the water-soluble lipid fraction of the CHCl3/MeOH extract of the starfish Linckialaevigata. On the basis of chemical and spectroscopic findings, the structure of 1 has been elucidated. Negative-ion FABMS provided important information concerning both the structure of the sugar moiety and the molecular mass of the ganglioside. On the other hand, positive-ion FABMS/MS of [M + Na]+ ions obtained in the positive-ion FABMS of the ceramide lactoside (4) derived from 1 indicated the structure of the fatty acid chain of the ceramide moiety. 1 represents a new ganglioside molecular species possessing a 2→11-linked tandem-type disialosyl moiety.
