Abstract

Radioactive choline is incorporated by pneumococcus (strain R36A) into a polymeric substance from which it can be quantitatively recovered as free choline, after hydrolysis by strong acid. The polymeric substance is insoluble in lipid solvents and can be degraded by periodate. Fractionation studies and chemical analyses suggest that choline is linked to a polysaccharide component of pneumococcal cell wall.

摘要

放射性胆碱被肺炎球菌（R36A菌株）掺入一种聚合物质中，经强酸水解后，胆碱能从该聚合物质中以游离胆碱的形式定量回收。该聚合物质不溶于脂质溶剂，可被高碘酸盐降解。分级分离研究和化学分析表明，胆碱与肺炎球菌细胞壁的多糖成分相连。
