Mode of Action of Hydrogen Peroxide
Hydrogen peroxide, which is a strong oxidant, is widely used in many fields. The mode of action of hydrogen peroxide is unique and valuable for investigation.
Hydrogen peroxide often plays a role in chemical reactions by virtue of its easy decomposition characteristics. Its decomposition produces hydroxyl radicals (· OH), which are highly active and have strong oxidation ability. In many oxidation reactions, hydroxyl radicals can quickly react with reactant molecules, and accelerate the reaction process through hydrogen extraction, addition, etc. For example, in organic synthesis, the hydroxyl radicals produced by the decomposition of hydrogen peroxide can be used to achieve oxidation of specific organic matter and achieve specific chemical transformation.
In biological systems, the mode of action of hydrogen peroxide cannot be ignored. An appropriate amount of hydrogen peroxide can be used as a signaling molecule to participate in the signaling process in cells. However, if too much hydrogen peroxide accumulates, it will cause oxidative damage to cells. This is due to the large number of hydroxyl radicals produced by too much hydrogen peroxide, which will attack biological macromolecules such as cell membranes, proteins and nucleic acids. Unsaturated fatty acids in cell membranes are susceptible to hydroxyl radical attack and lipid peroxidation, which destroys the integrity and function of cell membranes; amino acid residues in protein molecules are modified by hydroxyl radicals, which will cause changes in protein structure and function; bases in nucleic acid molecules may also be attacked by hydroxyl radicals and mutate, affecting the accurate transmission and expression of genetic information.
In the environmental field, the action mode of hydrogen peroxide is reflected in its use in wastewater treatment and other aspects. It can oxidize and decompose organic pollutants in wastewater, and gradually degrade complex organic pollutants into simple inorganic substances through the strong oxidation of hydroxyl radicals, thereby realizing wastewater purification and reducing the harm of pollutants to the environment. In short, hydrogen peroxide has an important impact in many fields such as chemistry, biology, and the environment due to its unique decomposition mode of highly active hydroxyl radicals.
