Definition: |
A branched hexasaccharide consisting of a linear tetrasaccharide comprising beta-D-galactose, two L-glycero-alpha-D-manno-heptose (L-alpha-D-Hep) residues and a 3-deoxy-alpha-D-manno-oct-2-ulose (alpha-Kdo) residue linked in sequence (1->3), (1->3) and (1->5), to the L-alpha-D-Hep residue proximal to the reducing end is also linked (1->4) a beta-D-glucose residue, while the alpha-Kdo residue also carries a second alpha-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.
