Structural investigation of Klebsiella serotype K36 polysaccharide.

Klebsiella D36 capsular polysaccharide has been investigated by methylation, Smith-periodate oxidation and partial hydrolysis techniques. The structure was found to consist of a hexasaccharide repeating unit as shown. The anomeric configurations of the sugar residues were determined by 1H and 13Cn.m.r.spectroscopy on isolated oligomers obtained during the degradative studies and on the intact polysaccharide.
