The specific substance from Pneumococcus type 34(41). The structure of a phosphorus-free repeating unit

Abstract
A pentasaccharide repeating unit was isolated from the specific substance from Pneumococcus type 34(41) by alkali hydrolysis followed by enzymic dephosphorylation. The pentasaccharide was O-D-galacto-furanosyl-(1[forward arrow] 3)-O-[alpha]-D-glucopyranosyl-(1[forward arrow]2)-O-D-galactofuranosyl-(1[forward arrow]3)-O-[alpha]-D-galactopyranosyl-(1[forward arrow]2)-ribitol.
