Particulate fractions of Micrococcus lysodeikticus incubated with UDP-D-[14C]glucose incorporated radioactivity into a chloroform - methanol-soluble, low-mol. wt. compound, and into a polymer. The low-mol. wt. compound consisted of a glucolipid that was extremely labile to mild acid hydrolysis with the formation of D-[14C]glucose, and to mild alkali, yielding 14C-labeled alpha-D-glucopyranose 1,2-phosphate
与UDP-D- [14C]葡萄糖孵育的溶菌微球菌的微粒级分将放射性结合到氯仿-溶于甲醇的低分子化合物中。重量 化合物,然后变成聚合物。低摩尔。重量 该化合物由对中度酸水解形成D- [14C]葡萄糖和对中度碱极其不稳定的糖脂组成,产生14C标记的α-D-吡喃葡萄糖1,2-磷酸和D-葡萄糖2-磷酸。标记的糖脂从DEAE-纤维素柱上洗脱出来的盐浓度高于合成的Ficaprenyl(D-葡萄糖基吡喃糖基磷酸)所需要的盐浓度,并且在tlc中迁移速度比后者化合物慢得多。 ,但不是由C55-二烷基磷酸酯制成。
