title: Acidic sphingoglycolipids in invertebrate nervous tissue: presence of several kinds of sphingophosphonoglycolipids in the nervous tissue of Aplysia kurodai, a sea gastropod.
abstract: Several hitherto unknown sphingophosphonoglycolipids were identified in the lipid extract from the nervous tissue, nerve fibers and ganglia of Aplysia kurodai, which has only a small amount of gangliosides, if any. The most abundant sphingophosphonoglycolipids of the nerve fiber (FGL-VII) and ganglion (GGL-V) are ceramide bis(2-aminoethylphosphono)-pentaosides. Their oligosaccharide moieties consist of 1 mol each of glucose, 3-O-methylgalactose and galactosamine and 2 mol of galactose. Another main glycolipid (FGL-II) may be ceramide mono(2-aminoethylphosphono)-pentaoside which contains 1 mol each of glucose, galactosamine and fucose and 2 mol of galactose as its oligosaccharide moiety.
