Incorporation of carbon-14-labeled phenylalanine into brain protein of newborn pigs falls sharply within 24 hours after birth. This decrease is related to the time of birth rather than the gestational age of the piglets, although the latter is also associated with a gradual decrease in brain protein synthesis.
新生猪脑中碳-14标记的苯丙氨酸掺入量在出生后24小时内急剧下降。这种下降与出生时间有关,而非仔猪的胎龄,尽管胎龄也与脑蛋白合成的逐渐减少有关。
