title: Changes in glutamine synthesis activity in the different organs of developing rats.
abstract: The changes experienced by the glutamine synthetase activity in the liver, kidney, striated muscle, adipose tissue, brain, stomach, small intestine and skin of developing rats have been estimated. Skin and stomach enzymes attained the adult values in the late foetal period. Striated muscle, intestine and kidney glutamine synthetase belonged to the neonatal cluster, while liver and brain rose to values comparable to those of adults in late suckling. Glutamine synthesis between different organs of the rat during development matures soon after birth, gaining a considerable importance that helps to compensate the lack of availability of other nitrogen transport systems between peripheral and splanchnic bed organs in developing rats.
