alpha-Neu5Ac-(2->3)-[beta-D-Gal-(1->3)-beta-D-GalNAc-(1->4)]-beta-D-Gal-(1->4)-beta-D-Glc-(1<->1')-Cer(d20:1)(1-)
alpha-neu5ac-(2->3)-[beta-d-gal-(1->3)-beta-d-galnac-(1->4)]-beta-d-gal-(1->4)-beta-d-glc-(1<->1')-cer(d20:1)(1-)
An anionic ganglioside that is the conjugate base of α-Neu5Ac-(2→3)-[β-<small>D</small>-Gal-(1→3)-β-<small>D</small>-GalNAc-(1→4)]-β-<small>D</small>-Gal-(1→4)-β-<small>D</small>-Glc-(1↔1')-Cer(d20:1) arising from deprotonation of the neuraminosyl carboxy group; major species at pH 7.3.
