The molecule is a ganglioside derivative derived from a GM1 skeleton linked to a GD1a skeleton through their respective amino nitrogen atoms by an adipoyl (hexanedioyl) group. It derives from a ganglioside GM1 and an alpha-NeuNAc-(2->3)-beta-D-Gal-(1->3)-beta-D-GalNAc-(1->4)-[alpha-NeuNAc-(2->3)]-beta-D-Gal-(1->4)-beta-D-Glc-(1<->1')-Cer.
