The molecule is a branched derivative heptasaccharide consisting of the tetrasaccharide derivative beta-D-galactosyl-(1->4)-N-acetyl-beta-D-glucosaminyl-(1->3)-beta-D-galactosyl-(1->4)-D-glucose where the galactosyl residue at the non-reducing end has alpha-L-fucosyl and N-acetyl-alpha-D-galactosaminyl residues attached at the 2- and 3-positions respectively and the glucosaminyl residue has an alpha-L-fucosyl residue attached at the 3-position. It is a galactosamine oligosaccharide, a glucosamine oligosaccharide and a heptasaccharide derivative.
