title: Structures of some new complex gangliosides of fish brain.
abstract: Three novel trisialogangliosides of fish brain, GT3, GT2 and GT1c, have been isolated in their intact forms and their structures characterized. The discovery of these ganglioside species provides essential links for a new possible biosynthetic pathway leading to the major tetrasialoganglioside, GQ1c, of the fish brain.
