Участь вільних амінокислот в адаптації риб до дії іонів важких металів

Abstract

The role of particular amino acids in the resistance of fish organism to the influence of heavy metals (Mn, Zn, Cu, Pb) through their specific participation in the processes of the synthesis an energy generation in the experimental condition were investigated. It was show that the leading role in this process in carp organism have glycine, the content of which in the muscles of the control fish is quite high. Among other amino acids, it should be noted the growth both in the muscles and in the liver of experimental fish the amount of sulfurcontaining. An important role in the detoxification of ammonia, which is formed under the influence on the organism of carp the elevated metal concentrations, belongs to aspartic and glutamic acids. In our studies, the content of free amino acids in the liver and muscle of fish is reduced by the action of metal ions. In general, the dynamics of free amino acids in carp tissues reflects the general tendencies of metabolism in its organism.
