alpha-N-acetylneuraminosyl-(2->3)-[beta-D-galactosyl-(1->3)-N-acetyl-beta-D-galactosaminyl-(1->4)]-beta-D-galactosyl-(1->4)-beta-D-glucosyl-(1<->1')-ceramide(1-)
alpha-n-acetylneuraminosyl-(2->3)-[beta-d-galactosyl-(1->3)-n-acetyl-beta-d-galactosaminyl-(1->4)]-beta-d-galactosyl-(1->4)-beta-d-glucosyl-(1<->1')-ceramide(1-)
An anionic ganglioside that is the conjugate base α-<em>N</em>-acetylneuraminosyl-(2→3)-[β-<small>D</small>-galactosyl-(1→3)-<em>N</em>-acetyl-β-<small>D</small>-galactosaminyl-(1→4)]-β-<small>D</small>-galactosyl-(1→4)-β-<small>D</small>-glucosyl-(1↔1')-ceramide arising from deprotonation of the neuraminosyl carboxy group; major species at pH 7.3.
