Adaptive Mechanism for the Regulation of Animal Food Behavior

Abstract

AbstractThe article presents the results of the experiment on the effect of different forms of balanced diets in the nutrition of laboratory animals on the content of free amino acids in tissues and organs of animals. It is proved that the sum of free amino acids in the organs of animals on the adjusted diet is lower than with the deficit of one of the essential amino acids. In the liver, the total concentration of amino acids is lower than in animals of 1, 2 and 4 groups - 128.2 versus 152.4; 143.5 and 177.8 mg %, respectively. If we consider the concentration of free amino acids relative to their consumption with food, then this ratio will be the lowest in blood plasma, muscle and liver of animals on an adjusted diet. The correct ratio of amino acids on the adjusted diet promoted more efficient use of free amino acids for the synthesis of body proteins. In animals that received an adjusted diet, the total sum of free amino acids in blood plasma and muscles did not differ significantly from that of animals in groups 1, 2, 3, 4, despite the fact that they consumed 50%, 29% and 43% protein more, respectively. The level of free amino acids in muscles in all forms of amino acid balance turned out to be similar. An optimal set of amino acids is transported to the muscles as a substrate for the synthesis of intracellular protein structures. Barrier and regulatory functions are provided by plasma membrane of myocytes.KeywordsBloodLiverMusclesAmino acidsProtein synthesis
