An O-specific polysaccharide composed of L-rhamnose was obtained on mild acid degradation of the Yersinia rohdei lipopolysaccharide. On the basis of methylation studies and 13C NMR data, the O-specific polysaccharide is shown to be a linear L-rhamnan built up of trisaccharide repeating units of the following structure: →3)-α-L-Rhap-(1→3)-α-L-Rhap-(1→3)-β-L-Rhap-(1→ The structure was confirmed by calculations with the use of the known glycosylation effect on 13C chemical shifts.
