di-(d-mannosylated) alpha-d-manp-(1->3)-[alpha-d-manp-(1->6)]-beta-d-manp-(1->4)-beta-d-glcpnac-(1->4)-d-glcpnac
An amino heptasaccharide that is MAN-3 glycan, α-<small>D</small>-Man<em>p</em>-(1→3)-[α-<small>D</small>-Man<em>p</em>-(1→6)]-β-<small>D</small>-Man<em>p</em>-(1→4)-β-<small>D</small>-Glc<em>p</em>NAc-(1→4)-<small>D</small>-Glc<em>p</em>NAc, in which either (a) two hydroxy groups in one of the terminal mannosyl groups have each undergone glycosylation with a molecule of <small>D</small>-mannopyranose, or (b) one of the hydroxy groups has undergone dimannosylation. The position of the additional mannosyl groups is not known. In the structure shown, either two of the R atoms each represent a <small>D</small>-mannopyranosyl group, or one of the R atoms represents a di-<small>D</small>-mannosyl group; all remaining R atoms = H.
