PolysacDB ID1459
Carbohydrate NameLipopolysaccharide   (Drugpedia)
Carbohydrate ClassLipopolysaccharide
MicrobeHaemophilus ducreyi   (NCBI Taxonomy)   (Drugpedia)
Basic StructureIt consist of an oligosaccharide core ketosidically linked via a 3-deoxy-D-manno-octulosonic acid (Kdo) residue to the lipid A region. The oligosaccharide core characteristic of these bacteria has been divided into two regions: (i) an inner core, consisting of three L-glycero-D-manno-heptose (Hep) residues and one phosphorylated Kdo residue, and (ii) an outer core, with one or more heterogeneous oligosaccharide branches containing mainly galactose (Gal) and glucose (Glc) residues
