Abstract:
The structure of the capsular polysaccharide from Klebsiella type K43 has been investigated using sugar and methylation analysis, uronic acid degradation, and NMR spectroscopy on the native and the O-deacetylated polysaccharide. It is concluded that the polysaccharide is composed of pentasaccharide repeating units with the structure [formula: see text] The polysaccharide contains approximately 0.4 equiv of O-acetyl group per repeating unit, located at a primary position.
