ABSTRACT
In this chapter, we studied the influence of spatially hindered phenols as adaptogens and plant growth and development regulators (PGRs) on the intensity of free radical processes, an indication of whose is the intensity of lipid peroxidation (LPO) in biological membranes, particularly the membranes of mitochondria stressful effects lead to a shift in antioxidant pro-oxidant equilibrium in the direction of increasing the generation of reactive oxygen species (ROS) by mitochondria. As a result, a 3–4-fold increase in the fluorescence intensity of LPO products is observed in the membranes of these organelles. Spatially hindered phenols reduce the intensity of LPO to control values, which contributes to the preservation of high functional activity of the mitochondria. Prevent dysfunction of mitochondria is associated with an increase in the sustainability of plant and animal organisms to the action of stress factors.
