[Antigenic polysaccharides of bacteria. 33. The structure of O-specific polysaccharide chain of lipopolysaccharide from Pseudomonas cepacia serotype 6].
On mild acid degradation of the Pseudomonas cepacia serotype 6 lipopolysaccharide, the O-specific polysaccharide was obtained, which contains D-mannose and D-galactose residues in the ratio approximately 1:1, as well as O-acetyl groups. On the basis of 1H and 13C NMR analysis, calculation of specific optical rotation, and methylation, it was concluded that the polysaccharide possesses the following structure: (formula; see text) Regularities in glycosidation effects in 13C NMR spectra of 1,3-linked disaccharides containing furanoside residues are discussed.
