The molecule is an amino oligosaccharide (heptadecasaccharide) in which two alpha-D-mannose residues, each of which has linked to it a trisaccharide sequence of two beta-D-galactose residues and an N-acetyl-beta-D-glucosamine residue, are linked (1->4) and (1->6) to the mannose residue of a trisaccharide sequence of beta-D-mannose, N-acetyl-beta-D-glucosamine and N-acetyl-D-glucosamine residues all linked (1->4). It is an amino oligosaccharide and a glucosamine oligosaccharide.
