Abstract
The structure of the O-antigen polysaccharide (PS) from Escherichia coli O77 has been determined. Sugar and methylation analysis together with 1H and 13C NMR spectroscopy were the main methods used. The PS is composed of tetrasaccharide repeating units with the following structure:-->2)-alpha-D-Manp-(1-->2)-beta-D-Manp-(1-->3)-alpha-D-GlcpNAc-(1-->6)-alpha-D-Manp-(1-->
摘要
大肠杆菌O77的O抗原多糖（PS）结构已被确定。主要使用的方法包括糖和甲基化分析以及1H和13C核磁共振光谱法。该PS由具有以下结构的四糖重复单元组成：→2）-α-D-甘露糖基-（1→2）-β-D-甘露糖基-（1→3）-α-D-葡萄糖胺基-（1→6）-α-D-甘露糖基-（1→
