The molecule is a branched amino nonasaccharide consisting of a chain of beta-D-galactose, N-acetyl-beta-D-glucosamine, beta-D-galactose, N-acetyl-beta-D-glucosamine, beta-D-galactose and D-glucose residues linked sequentially (1->3), (1->3), (1->4), (1->6) and (1->4), to the D-galactose residue nearest to the reducing end of which is also linked (1->3) a beta-D-galactosyl-(1->3)-N-acetyl-beta-D-glucosaminyl unit, and with also an L-alpha-fucosyl residue linked (1->3) to the N-acetyl-beta-D-glucosamine residue nearest to the reducing end. It is an amino nonasaccharide and a glucosamine oligosaccharide.
