Abstract
The acidic polysaccharide from Serratia marcescens serogroup O14:K12 was analyzed by means of chemical studies and NMR spectroscopy and its repeating unit structure found to be carbohydrate sequence [see text] O-Acetyl groups are proposed to be present in non-stoichiometric amounts on O-6 on one of the hexose residues in the main chain.
摘要
对粘质沙雷氏菌O14:K12血清群的酸性多糖进行了化学研究和核磁共振光谱分析，发现其重复单元结构为碳水化合物序列[见正文]。据推测，主链中一个己糖残基的O-6位上存在非化学计量量的O-乙酰基。
