The O-polysaccharide was obtained by a mild acid degradation of the lipopolysaccharide of Providencia alcalifaciens O29. Structural studies were performed using sugar and methylation analyses along with 1H and 13C NMR spectroscopy, including two-dimensional 1H, 1H COSY, TOCSY, ROESY, H-detected 1H, 13C HSQC and HMBC experiments. On the basis of the data obtained, the following structure of the branched tetrasaccharide repeating unit of the O-polysaccharide was established: [structure: see text].
通过对产碱普罗威登斯菌O29脂多糖进行温和酸降解获得了O-多糖。使用糖分析、甲基化分析以及1H和13C NMR光谱进行结构研究，包括二维1H、1H COSY、TOCSY、ROESY、H检测的1H、13C HSQC和HMBC实验。根据获得的数据，确定了O-多糖支链四糖重复单元的以下结构：[结构：见原文]
