A phosphorylated 2-keto-3-deoxyoctonic acid (KDO) was released from the lipopolysaccharides of Vibrio cholerae Ogawa and Inaba after strong acid hydrolysis. The phosphorylated KDO was identified by gas-liquid chromatography and mass spectrometry after reduction and permethylation as KDO-5-phosphate and an isomer of it being phosphorylated at position 7 or 8. After treatment with alkaline phosphatase, KDO was detected by gas-liquid chromatography and mass spectrometry. It was indistinguishable from authentic 2-keto-3-deoxy-D-manno-octonic acid.
在强酸水解后,磷酸化的2-酮-3-脱氧辛酸(KDO)从霍乱弧菌小川型和稻叶型的脂多糖中释放出来。经还原和全甲基化后,通过气液色谱和质谱鉴定该磷酸化的KDO为5-磷酸-KDO及其在7位或8位磷酸化的异构体。用碱性磷酸酶处理后,通过气液色谱和质谱检测到KDO。它与 authentic 2-酮-3-脱氧-D-甘露辛酮酸无法区分。 (注:这里“authentic”可译为“真实的、正宗的、标准的”等,具体意思需结合上下文确定,暂保留英文未译,因为不确定在此处最合适的中文表述)
