In the pregnant rat, dietary protein restriction reduces the transfer of 14C-labeled alpha-aminoisobutyric acid from the maternal blood into the fetus. One of the causes of this phenomenon is a reduced capacity of the placenta to release into the fetus alpha-aminoisobutyric acid taken up from the maternal blood.
在怀孕大鼠中,饮食蛋白质限制会减少母体血液中14C标记的α-氨基异丁酸向胎儿的转运。这种现象的原因之一是胎盘将从母体血液中摄取的α-氨基异丁酸释放到胎儿体内的能力降低。
