DefinitionA branched amino tetrasaccharide consisting of an N-acetyl-α-L-quinovosaminyl-(1→3)-N-acetyl-α-D-galacturonosaminyl-(1→3)-N-acetyl-α-L-quinovosamine trisaccharide unit, the galacturonosaminyl residue of which carries a further N-acetyl-α-L-quinovosaminyl residue via a (1→4) glycosidic linkage. Corresponds to the tetrasaccharide repeating unit of the capsular polysaccharide of Vibrio vulnificus MO6-24.
