Radical Processes in Cellular Structure

Abstract

In biological objects, natural and foreign radicals are distinguished. It is known that foreign radicals have a negative effect on the cells of living organisms. Unlike foreign radicals, natural radicals predominate in biological objects, which play a key role in the processes of cell life, in the reactions of biosynthesis, oxidative phosphorylation, regulation of lipid metabolism, mitosis, metabolism, etc. Every day, each cell generates a huge number of compounds with a naturally radical nature, which then participate in biochemical processes associated with the donation or acquisition of electrons. A significant role in radical oxidation-reduction. The reactions of the cell are carried out by coenzymes NAD, NADP, FAD, FMN, and also CoQ, capable of forming intermediate radical structures and charge transfer complexes (CTCs) in biological membrane censoring the transfer of energy and the transport of electrons in the cell's polyenzyme complexes.
