The specific capsular polysaccharide of Streptococcus pneumoniae type 33F (American type 70) is composed of D-galactose (5 parts), D-glucose (1 part), and O-acetyl (ca. 0.4 parts). Periodate oxidation, partial hydrolysis, and 1H and 13C nuclear magnetic resonance studies showed that the polysaccharide is a high molecular weight polymer of a repeating hexasaccharide unit having the structure: (Formula: see text).
