| Abstract: | The primary structure of the O-antigen of Escherichia coli O117 was shown by monosaccharide analysis, methylation analysis, and by 1D and 2D 1H and 13C NMR spectroscopy to be composed of linear pentasaccharide repeating units with the structure: -->3)-alpha-D-GalpNAc-(1-->4)-beta-D-GalpNAc-(1-->3)-alpha-L-Rhap- (1-->4)- alpha-D-Glcp-(1-->4)-beta-D-Galp-(1--> |
