Abstract
The structure of Citrobacter O23-specific polysaccharide has been shown by sugar and methylation analyses of the native and chemically degraded polysaccharide and by 1H- and 13C-n.m.r. spectroscopy to consist of the tetrasaccharide repeating-units: ----4)-alpha-D-Man-(1----2)-alpha-D-Man-(1----2)-beta-D-Man- (1----3)-alpha-D-GalNAc-(1----, 80% of which are substituted by O-acetyl groups.
摘要
通过对天然和化学降解多糖的糖分析、甲基化分析以及1H和13C核磁共振光谱分析表明，柠檬酸杆菌O23特异性多糖的结构由四糖重复单元组成：----4)-α-D-甘露糖-(1----2)-α-D-甘露糖-(1----2)-β-D-甘露糖-(1----3)-α-D-N-乙酰半乳糖胺-(1----，其中80%被O-乙酰基取代。
