The molecule is an amino oligosaccharide comprising 4 fucose, 2 galactose, 4 N-acetyl glucosamine and 3 mannose residues arranged as two alpha-L-Fuc-(1->2)-beta-D-Gal-(1->4)-[alpha-L-Fuc-(1->3)]-beta-D-GlcNAc-(1->2)-alpha-D-Man brached chains linked (1->3) and (1->6)to a beta-D-Man-(1->4)-beta-D-GlcNAc-(1->4)-D-GlcNAc trisaccaride chain. It has a role as an epitope. It is a glucosamine oligosaccharide and an amino oligosaccharide.
