The structure of the acidic polysaccharide from Serratia marcescens serogroup O1 has been investigated. NMR spectroscopy together with sugar and methylation analysis have been used as well as a uronic degradation. The polysaccharide consists of pentasaccharide repeating units having the following structure. (sequence see text) The polysaccharide also contains one equivalent of O-acetyl groups per repeating unit present on, inter alia, a hydroxymethyl group.
对粘质沙雷氏菌O1血清群酸性多糖的结构进行了研究。采用了核磁共振光谱法、糖分析、甲基化分析以及糖醛酸降解法。该多糖由具有以下结构的五糖重复单元组成。(序列见正文)该多糖每个重复单元还含有一个当量的O-乙酰基,尤其存在于羟甲基上。
