Abstract
IN the fœtal liver of mammals there is little or no activity of the following enzymatic systems : glucose-6-phosphatase1, uridine diphosphoglucose dehydrogenase, and glucuronyltransferase2, phenylalanine transaminase, tyrosine transaminase and phenylalanine hydroxylase3. Hence these enzymes reach the normal levels of activity during the first period of extra-uterine life, and for some of them it seems that this process is regulated or accelerated by the adrenocortical hormones.
