heating in dilute acid, 3-deoxy- d -manno-oct-2-ulosonic acid (KDO) is converted into 2,7-anhydro-3-deoxy-α- d -manno-2-octulofuranosonic acid and 5-( d -erythro-1,2,3-trihydropropyl)-2-furoic acid. The former is unreactive to periodic acid-thiobarbituric acid and to semicarbazide, and its formation explains the depressed estimates of KDO in lipopolysaccharides. Formation of the furoic acid can lead to high
摘要在稀酸中加热时,将3-deoxy-d-manno-oct-2-ulosonic acid(KDO)转化为2,7-anhydro-3-deoxy-α-d-manno-2-octulofuranosonicacid和5- (d-赤型-1,2,3-三氢丙基)-2-糠酸。前者与高碘酸-硫代巴比妥酸和氨基脲不反应,其形成解释了脂多糖中KDO的估算值降低。糠酸的形成可导致使用氨基脲测定法的高估计值。两种产物都不能由5-O-糖基-KDO形成。
