Abstract
Transport of D-fructose and D-galactose across the plasma membrane of isolated rat hepatocytes was followed for the net entry of sugars into sugar-free cells at 20 degrees C. Initial rates of transport showed a Michaelis-Menten dependency on sugar concentration, and transport was inhibited by 3-O-methyl-D-glucose in the external medium.
摘要
在20℃下，跟踪D-果糖和D-半乳糖通过分离的大鼠肝细胞质膜的转运情况，以观察无糖细胞中糖的净进入量。转运的初始速率显示出对糖浓度的米氏依赖性，并且外部培养基中的3-O-甲基-D-葡萄糖会抑制转运。
