1、根据指示剂变色范围公式,pH=pKHin±1,各种指示剂的变色范围应为2个pH单位,故甲基橙理论变色范围是pH在2.4~4.4,和实际一致。

然而,在大鼠盲肠和结肠中,1.0单位pH变化时的缓冲容量高于0.5单位pH变化时的缓冲容量(图1a);这可归因于发酵产物中存在多种缓冲物质,例如具有不同pka值的短链脂肪酸。值得注意的是,猪的体液中没有观察到这种行为(图1c),这可能是因为盲肠发酵在大鼠营养(粪噬)中比在猪中更重要。在兔液中也进行了类似的观察(图1...

At pH 6.0, DAC (pKa = 6.64) exists in a neutral form, which enhances the release rate because of the loss of ionic interaction between DAC and cationic LDH layers. However, at pH 7.4, because of ionic interaction between DAC anions and cationic LDH layers DAC-LDH structure is ...
