Abstract
Glutamine-dependent carbamyl phosphate synthetase activity has been demonstrated in fetal liver, gut, carcass, and brain and in the placenta of the 19-day pregnant rat. The widespread distribution of this enzyme within the conceptus indicates that even the first step in the de novo biosynthesis of pyrimidines can occur in situ. It also suggests that formation of nucleic acids by the conceptus during fasting may be supported by products of maternal protein catabolism.
