Abstract

The structure of the group-specific polysaccharide of group E Streptococcus was determined by methylation, periodate oxidation, and partial methanolysis, and the configuration of the anomeric linkages by 1H- and 13C-n.m.r. spectroscopy. The trisaccharide repeating unit----2)-alpha-L-Rhap-(1----3)-[beta-D-Glcp-(1----2)]-alpha-L -Rhap-(1----was determined.

摘要

通过甲基化、高碘酸盐氧化和部分甲醇解确定了E群链球菌群特异性多糖的结构，并通过1H-和13C-核磁共振光谱确定了异头键的构型。确定了三糖重复单元----2)-α-L-鼠李糖-(1----3)-[β-D-葡萄糖-(1----2)]-α-L-鼠李糖-(1---- 。
