description: "A polysaccharide derivative composed of a backbone of alpha-D-Gal-(1->3)-[alpha-L-Fuc-(1->2)]-beta-D-Gal-(1->3)-alpha-D-GalNAc-(1->3)-D-GalNAc branched pentasaccharide repeating units that are joined to each other via alpha(1->2)-linkages; corresponds to the O-antigen repeat unit structure of E. coli O86:B7."
