[Relationship between bound and free amino acids in the brain of growing rats].
Total pool of glutamate, glutamine and GABA in the hemispheres increases during postnatal life of rats, the increase being due to that in free and bound forms of amino acids. In the cerebellum of 1-day rats, the content of free and bound glu, gln asp, GABA, bound ala and free gly is lower, whereas the level of free glu and ala, bound gly is higher than in mature animals. To the end of the 1st week, total amino acid content decreases, except GABA, which is increased. Aminon acid content begins to increase at the 21th and 28th days of postnatal life.
