Abstract:
The structure of the O-antigenic polysaccharide part of the lipopolysaccharide isolated from Vibrio cholerae O10 has been determined. The main method used has been 1H- and 13C-NMR spectroscopy. Sugar and methylation analyses were also applied to the polysaccharide. The tetrasaccharide repeating unit of the polysaccharide was found to have the following structure: -->3)-alpha-D-ManpNAc-(1-->4)-beta-D-GlcpA-(1-->3)-beta-D-Ga lp-(1-->3)-beta-D-GlcpNAc-(1-->.
