Influence of the pH on the absorption rate of sugars by rat intestine in vivo has been revised by means of a technique for intestinal lumen perfusion with 1 minute absorption periods. Absorption at pH 2.5, 5, 7, 8.5, and 10 has been comparied in each animal. Absorption rate of D-glucose, D-galactose and D-fructose is highest at pH 7 and decreases at the lower or higher pH values. The pH does not affect the absorption of D-arabinose. The pH effect is attributed to changes in the transport system for sugars.
通过一种采用1分钟吸收期的肠腔灌注技术，对pH值对大鼠体内肠道吸收糖速率的影响进行了修正。在每只动物中比较了pH值为2.5、5、7、8.5和10时的吸收情况。D-葡萄糖、D-半乳糖和D-果糖的吸收速率在pH值为7时最高，在较低或较高pH值时降低。pH值不影响D-阿拉伯糖的吸收。pH效应归因于糖转运系统的变化。
