[13C-NMR spectrum of O-specific polysaccharide from the lipopolysaccharide of Yersinia pseudotuberculosis of serotype III].

A 13C NMR spectrum of O-specific polysaccharide isolated from Yersinia pseudotuberculosis III serovar lipopolysaccharide has been interpreted. This allowed to define more precisely the configuration of glycosidic bonds and to confirm the structure of the repeating unit of the specific polysaccharide which was earlier established by other methods.
