The structure of the Pneumococcus type 19A (57) capsular polysaccharide has been reinvestigated by using methylation analysis and n.m.r. spectroscopy. It is composed of residues of 2-acetamido-2-deoxy-D-mannose, D-glUCOSe, L-rhamnose, and phosphate in the molar ratios of 1:l: 1:l. The polysaccharide
The capsular polysaccharide from Streptococcus pneumoniae Type 23 (S-23) was found to contain D-galactose, D-glucose, L-rhamnose, glycerol, and phosphorus in the ratios of 1: 1: 2:0.6: 1. Methylation analysis provided information about the linkages of the different sugar units. The sequence of the d
