Abstract:The structure of the capsular antigen from Pneumococcus type 26 has been determined by using methylation analysis, periodate-oxidation studies, and n.m.r. spectroscopy of the original and the dephosphorylated product. It is concluded that the polysaccharide is composed of repeating-units having the following structure.
