beta-D-Galp-(1->3)-beta-D-GalpNAc-(1->4)-[alpha-Neup5Ac-(2->3)]-D-Galp-yl group
beta-d-galp-(1->3)-beta-d-galpnac-(1->4)-[alpha-neup5ac-(2->3)]-d-galp-yl group
A tetrasaccharide glycosyl group consisting of β-<small>D</small>-galactosyl, β-<small>D</small>-<em>N</em>-acetyl-galactosaminyl and <small>D</small>-galactosyl residues linked sequentially (1→3) and (1→4), to the <small>D</small>-galactosyl residue at the reducing end is also linked (2→3) an <em>N</em>-acetyl-α-neuraminyl residue.
