Abstract
The specific capsular polysaccharide produced by Streptococcus pneumoniae type 9V (American type 68) is composed of D-glucuronic acid (1 part), D-galactose (1 part), 2-acetamido-2-deoxy-D-mannose (1 part), D-glucose (2 parts), and O-acetyl (1.6 parts). Methylation, periodate oxidation, optical rotation, and nuclear magnetic resonance studies, and partial hydrolysis showed that the polysaccharide is an unbranched high molecular weight linear polymer of a partially O-acetylated pentasaccharide repeating unit having the structure indicated below.
