The structure of the O-specific side chain of the E. coli O26 lipopolysaccharide has been investigated. Based on sugar and methylation analyses, and 2D NMR spectroscopy employing HMBC experiments, it is concluded that the polysaccharide is composed of trisaccharide repeating units having the followi

β¦ Synopsis
The structure of the capsular antigen of E. coli K26 has been found by a combination ofchemical and spectroscopic techniques to be of the "5+ I" type shown. An important step was the simultaneous separation and identification of a mixture of neutral and acidic oligosaccharides by g.1.c. c.i.-m.s.
