| Definition: |
A branched amino oligosaccharide that is an undecasaccharide derivative consisting of a linear octasaccharide comprising two N-acetyl-α-neuraminic acid residues, β-D-galactose, N-acetyl-β-D-galactosamine and β-D-galactose residues, two L-glycero-α-D-manno-heptose (L-α-D-Hep) residues and a 3-deoxy-α-D-manno-oct-2-ulose (α-Kdo) residue linked in sequence (2→8), (2→3), (1→3), (1→4), (1→3), (1→3) and (1→5), to the L-α-D-Hep residue proximal to the reducing end is also linked (1→4) a β-D-glucose residue, while the galactose residue proximal to the reducing end also carries an N-acetyl-α-neuraminic acid residue via a (1→3) linkage and the α-Kdo residue also carries a second α-Kdo residue linked (2→-4). One of a number of chemoenzymatically synthesised oligosaccharides composed of the inner core oligosaccharide of Campylobacter jejuni extended by various ganglioside mimics. |
