The molecule is a high mannose oligosaccharide consisting of three alpha-D-mannopyranose residues, a beta-D-mannopyranose residue, a 2-acetamido-beta-D-glucopyranosyl residue and a 2-acetamido-alpha-D-glucopyranosyl residues joined in sequence by (1->2), (1->2), (1->3), (1->4), and (1->4) glycosidic linkages, and in which the second mannosyl group from the chitobiose moiety is substituted at position 6 by a alpha-D-mannopyranosyl-(1->6)-[alpha-D-mannopyranosyl-(1->2)-alpha-D-mannopyranosyl-(1->3)]-alpha-D-mannopyranosyl group. It is a high-mannose oligosaccharide and an amino decasaccharide.
