Markers of oxidative stress in the blood of quails under the influence of selenium nanoparticles

Abstract

Due to the action of various physicochemical factors on the body, there are changes in the functioning of the antioxidant defense system, which is able to activate oxidative stress, leading to damage to important biomolecules such as proteins, lipids and DNA, as well as disruption of energy processes in cells. The main targets of reactive oxygen species are proteins and lipids, which are part of cell membranes and cytoplasm. Indicators of oxidative modification of proteins, lipoperoxidation, and activity of enzymes of the antioxidant system are used as markers which characterize metabolic processes in the body and the use of biologically active drugs in livestock and poultry.
