Abstract
- When mono-, di- and triacetins are incubated with sacs of rat everted intestine, they enter the epithelial cells and are hydrolysed to free glycerol and acetic acid.2. The rate-limiting step in the process is the entry of glyceride into the epithelial cell.3. The three acetins enter the epithelial cell at the same rate, and the mechanism of this remains unknown.4. The acetate released appears in higher concentrations on the serosal side, and the relation of this to the mechanism for transfer of volatile fatty acids is discussed.5. It is not necessary to postulate a special mechanism for entry of volatile fatty acids into the cell.
摘要
当单乙酸甘油酯、二乙酸甘油酯和三乙酸甘油酯与大鼠外翻肠囊一起温育时，它们进入上皮细胞并被水解为游离甘油和乙酸。
该过程中的限速步骤是甘油酯进入上皮细胞。
三种乙酸甘油酯以相同的速率进入上皮细胞，其机制尚不清楚。
释放出的乙酸在浆膜侧以更高的浓度出现，并讨论了其与挥发性脂肪酸转运机制的关系。
没有必要假定挥发性脂肪酸进入细胞存在特殊机制。
