Abstract
Membrane vesicles prepared from the midguts of Philosamia cynthia larvae (Lepidoptera) show a concentrative uptake of phenylalanine in the presence of salt gradients. Unlike mammalian intestines, the highest accumulation of the amino acid occurs with a potassium salt gradient. Glucose is very poorly permeable across the vesicles.
摘要
从樗蚕幼虫（鳞翅目）中肠制备的膜囊泡在存在盐梯度的情况下显示出苯丙氨酸的浓缩摄取。与哺乳动物肠道不同，氨基酸的最高积累发生在钾盐梯度存在时。葡萄糖透过这些囊泡的通透性很差。
