A branched octasaccharide glucosaminyl group consisting of a linear chain of β-<small>D</small>-mannose, <em>N</em>-acetyl-β-<small>D</small>-glucosamine and <em>N</em>-acetyl-<small>D</small>-glucosaminyl residues all linked (1→4), to the mannose residue of which are also linked (1→3) and (1→6) respectively a 6-<em>O</em>-phosphono-α-<small>D</small>-mannosyl-(1→2)-α-<small>D</small>-mannosyl disaccharide unit and an α-<small>D</small>-mannosyl-(1→3)-[α-<small>D</small>-mannosyl-(1→6)]-α-<small>D</small>-mannosyl branched trisaccharide unit.
