The specific substance from Pneumococcus type 34 (41). The phosphodiester linkages

The phosphate groups in the type-specific substance S.34 from Pneumococcus type 34 (U.S. type 41) were shown to join the hydroxyl group at position 1 or 5 of ribitol and the hydroxyl group at position 3 of a d-galactofuranosyl residue in the next repeating unit. 2. A partial structure of the type-specific substance was derived. 3. New syntheses of d-galactose 2-phosphate and d-galactose 3-phosphate are described.
