The structures of the capsular polysaccharides elaborated by Klebsiella types 8 (K8) and 82 (K82) have been reinvestigated. N.m.r. spectroscopy of the original and chemically modified polysaccharides was the principal method used. It is concluded that the polysaccharides are composed of repeating un

✦ Synopsis
The structure of the capsular polysaccharide from Klebsiellu type K38 has been reinvestigated. It is composed of pentasaccharide repeating units of the structure given below. In this structure, Sug stands for a 4-deoxy-three-hex-4-enopyranosyluronic acid group, most probably having the P-L configuration.
'H NMR studies further indicate that this group assumes the lH2 conformation.
