Description: The molecule is a branched oligosaccharide phosphate comprising a D-galactose residue, a D-glucose residue, an N-acetyl-D-glucosamine residue, two L-glycero-D-manno-heptose residues (one of which is phosphoethanolamine-substituted on O-3), with linkages as shown and with a 3-deoxy-D-manno-oct-2-ulosonic acid (2-keto-3-deoxy-D-mannooctanoic acid, Kdo) residue at the reducing end. Corresponds to the lgtA mutant of the core oligosaccharide of Neisseria meningitidis. It is an oligosaccharide phosphate and an amino hexasaccharide.
