Hydrogen Peroxide Bactericidal
On the bactericidal effect of hydrogen peroxide
The world is called hydrogen peroxide, which is unique and has attracted much attention in sterilization.
Hydrogen peroxide has strong oxidative properties. In its molecular structure, the oxygen-oxygen single bond is relatively fragile, and it is easy to break and release reactive oxygen atoms. This reactive oxygen atom has strong oxidative power and can react with many key structures and components of bacteria.
The cell wall of bacteria is its barrier against external aggression. Hydrogen peroxide can cause oxidation of cell wall components, destroying the integrity of its structure and function. Make the cell wall no longer solid, and the bacteria are easily affected by external osmotic pressure, and then the bacteria are deformed and broken.
Furthermore, the cell membrane of bacteria is a key channel for the exchange of substances inside and outside the cell. Hydrogen peroxide acts on the cell membrane, and lipids and proteins in the oxide membrane cause changes in the permeability of the cell membrane. Key intracellular substances such as nucleic acids and enzymes are leaked, and bacteria lose their normal physiological functions.
And the genetic material nucleic acid of bacteria is essential for their survival and reproduction. The reactive oxygen species of hydrogen peroxide can attack nucleic acid bases, causing chain breaks or base modifications, causing the transmission and expression of bacterial genetic information to be disordered, unable to reproduce normally, and eventually death.
And many enzymes in bacteria are catalysts for their metabolism. Hydrogen peroxide can oxidize the active center of enzymes, change the spatial structure of enzymes, inactivate enzymes, block metabolism, and gradually kill bacteria.
Therefore, hydrogen peroxide acts on bacteria in multiple ways due to its strong oxidative properties, and has significant bactericidal effects. It has important applications in many fields such as hygiene, disinfection, medical and epidemic prevention, and is a powerful weapon for protecting human health.
