摘要：

The structure of the capsular polysaccharide from Klebsiella type 33 has been investigated. Methylation analysis, various specific degradations, graded hydrolysis with acid, and n.m.r. spectroscopy were,the principal methods used. It is concluded that the polysaccharide is composed of pentasaccharide repeating-units having the following structure. {A figure is presented} The D-galactopyranosyl group, with pyruvic acid linked as a ketal to O-3 and O-4, was degraded on treatment of the fully methylated polysaccharide with strong base. It is proposed that methyl pyruvate is eliminated, in an E2 type of reaction. © 1979.
