Significant of cathepsin B and its inhibitors in the regulation of metabolic processes in broiler under the influence of humic substances of nature

L. M. Stepchenko

The results of the allocation of the liver tissue of broiler chicken cysteine proteinases cathepsin B, which participates in the catabolic processes of protein metabolism, and its low molecular thermostable inhibitor. Studied regulatory effect of biologically active food additives humic origin "Gidrogumat" on the activity of cathepsin B and physicochemical characteristics of its endogenous inhibitor in the liver tissue of broiler chickens. Found that the action of humic substances in the body of chickens there are changes of the enzyme-inhibitor interactions in the realization of multifunctional multienzyme programs in liver cells, which ensures homeostasis of transition to a qualitatively new level, which corresponds to the higher productivity of animals.
