Description: The molecule is a lactam obtained via formal condensation of the carboxy group of an N-acetylneuraminyl residue and the amino group of the adjacent galactosamine residue in the ganglioside (2S,3R,4E)-3-hydroxy-2-(stearoylamino)octadec-4-en-1-yl N-acetylneuraminyl-(2->3)-beta-D-galactosaminyl-(1->4)-beta-D-glucoside. It is an oxaspiro compound, an azaspiro compound, a lactam and a ganglioside derivative.
