Abstract

Aim. The vital functions of living systems are regulated in two ways: chemical (biologically active substances, BACs) and physical factors. Cellular “redox-status” is maintained by specialized oxidant substances (OXs; free radicals, FRs) and antioxidants (AOs). These two classes also determine the functioning and integrity of living systems. This study examines the action mechanisms of natural AOs: tocopherol, prostaglandins, abscisic acid, brassinosteroids, steroids, and strigolactones. Results. The outlined mechanisms of BACs action describe how natural antioxidants tocopherol, prostaglandins, abscisic acid, steroids, brassinosteroids and strigolactones interact into the body at the molecular level, causing specific chemical and biological effects. Conclusions. Cellular “redox status” is maintained by specialized oxidant substances and antioxidants. This article describes the mechanisms of action of natural antioxidants without the involvement of protein receptors.
