The characteristics of the uptake of four naturally occurring amino acids, alanine, leucine, lysine and aspartate, by microvesicles prepared from the plasma membrane on the maternal surface of the human placenta were studied. Electron microscopy showed that a variety of fragments was interspersed between the vesicles and this heterogeneity probably accounted for the considerable variation in the results. Nevertheless, the properties of the uptake of amino acids were similar to those of vesicle preparations from other tissues. Insulin did not enhance the uptake of any of the amino acids.
对从人胎盘母体表面质膜制备的微囊摄取四种天然存在的氨基酸（丙氨酸、亮氨酸、赖氨酸和天冬氨酸）的特性进行了研究。电子显微镜显示，各种碎片散布在微囊之间，这种异质性可能是结果存在相当大差异的原因。然而，氨基酸摄取的特性与来自其他组织的微囊制剂相似。胰岛素并未增强任何一种氨基酸的摄取。
