Description: The molecule is an anionic ganglioside obtained by deprotonation of the neuraminosyl carboxy groups of ganglioside GQ1b (d18:1/C18:0); major species at pH 7.3. It is an alpha-Neu5Ac-(2->8)-alpha-Neu5Ac-(2->3)-beta-Gal-(1->3)-beta-GalNAc-(1->4)-[alpha-Neu5Ac-(2->8)-alpha-Neu5Ac-(2->3)]-beta-Gal-(1->4)-beta-Glc-(1<->1')-Cer(d18:1)(4-) and an anionic ganglioside. It is a conjugate base of an alpha-Neu5Ac-(2->8)-alpha-Neu5Ac-(2->3)-beta-Gal-(1->3)-beta-GalNAc-(1->4)-[alpha-Neu5Ac-(2->8)-alpha-Neu5Ac-(2->3)]-beta-Gal-(1->4)-beta-Glc-(1<->1')-Cer(d18:1/18:0).
