✦ Synopsis

The structure of the polysaccharide (S-21) elaborated by KZebsielZa pneumoniae ATCC 31314 has been investigated. NMR spectroscopy, sugar and methylation analysis, uranic acid degradation, and partial hydrolysis to oligosacccharides were the main methods used. In order to obtain good NMR spectra, the polymer was subjected to non-specific degradation by treatment with fuming hydrochoric acid. It is concluded that S-21 is composed of pentasaccharide repeating units with the following structure.
