Abstract
  1. The type-specific substance from Pneumococcus type 11A(43) is a polymer containing d-glucose, d-galactose, glycerol, phosphate and O-acetyl in the approximate molecular proportions 2:2:1:1:2. 2. Removal of the O-acetyl groups with ammonia gave a compound no longer active towards type 11A antiserum. 3. Treatment of S.11A with sodium borohydride, followed by hydrolysis with alkali yielded a phosphorus-free polysaccharide, whose structure was studied by methylation and by degradation with periodate. 4. Examination of S.11A and its de-O-acetyl derivative by periodate oxidation led to the partial structure (XI) for the type-specific substance, which thus has several features in common with S.18.
摘要
  1. 11A(43)型肺炎球菌的型特异性物质是一种聚合物,其含有d-葡萄糖、d-半乳糖、甘油、磷酸盐和O-乙酰基,分子比例约为2:2:1:1:2。2. 用氨去除O-乙酰基后得到的化合物对11A型抗血清不再有活性。3. 用硼氢化钠处理11A菌株,随后用碱水解,得到一种无磷多糖,其结构通过甲基化和高碘酸盐降解进行研究。4. 通过高碘酸盐氧化对11A菌株及其脱O-乙酰基衍生物进行检测,得出了型特异性物质的部分结构(XI),因此它与18型菌株有几个共同特征。
