    Abstract:
    In tests set up on young and old rats receiving isocaloric food rations with 9, 18 and 36 per cent of casein and by using glycin-20(14) the intensity of the tissular and serumal proteins biosynthesis was studied. An elevated content of protein in the rations of young animals, as distinct from the old ones, promotes activation of the assimilation and dissimilation phases of the proteinic metabolism. A low protein content in the rations finds its expression young animals in restriction of adaptation possibilities, in reduced intensity and in lowered intensity of the protein synthesis, although it continues at a higher level than in older animals. Differences in the level of the studied figures in young and old animals are pronounced least with the 18 per cent ration, this bearing proof to the absence of any essential age-specific difference in the requirements of the organism in food proteins, when its content in the rations is optimal.
