Description: The molecule is a branched amino heptasaccharide consisting of a linear sequence of N-acetyl-alpha-neuraminyl, beta-D-galactosyl, N-acetyl-beta-D-glucosaminyl, beta-D-galactosyl and N-acetyl-beta-D-glucosamine residues linked respectively (2->3), (1->3), (1->3) and (1->3), to each N-acetyl-beta-D-glucosamine residue of which is also linked an alpha-L-fucosyl residue, (1->4)-linked to the reducing-end residue and (1->3)-linked to the mid-chain one. It has a role as an epitope. It is an amino heptasaccharide and a glucosamine oligosaccharide.
