[The effect of vitamins A and E on the amino acid composition of proteins in different segments of the brain in aged animals].
The amino acids protein composition was studied in different segments of the brain in young (1.5 month old) and old (23-months) rats. The research covered also a short-lived action of vitamins A and E on the amino acids protein composition in the brain of 23-months old rats. The levels of the glutamic, aspartic acids, lysine, serine, of the sum of valine+methionine was found to be down, whereas the content of other amino acids proved invariable. After vitamins A and E loads the glutamic and aspartic acids in the brain segments under investigation was found to be up. In individual segments the content of lysine, thyrosine, valine+methionine experienced a certain normalization.
