[Distribution of free amino acids in the rat brain during ontogenesis].

Distribution of free amino acids reserves in the brain tissues, nuclei and mitochondria of rats is studied in ontogenesis dynamics. It is established that the content of most amino acids in tissues and mitochondria increases by the 6-month age, lowers in the brain tissues and subcellular structures by the 12-month age, decreases in the tissues and nuclei and grows in mitochondria of old animals. The reasons of disbalance in distribution of the reserves of free amino acids are under discussion.
