? Due to the constant contact with the outside world, including breathing (oxidation reaction), external pollution, radiation exposure and other factors, free radicals are constantly produced in the human body. Scientific research shows that cancer, aging or other diseases are mostly related to the production of excessive free radicals.
Comparison of skin oxidation by free radicals
Superoxide Dismutase (SOD) is a major antioxidant enzyme, which can scavenge superoxide radicals and play an important role in defending against oxygen toxicity, inhibiting senile diseases and preventing aging. SOD can specifically remove harmful free radicals in the body, thus alleviating the harm caused by free radical oxidation of some components in the body. Such as oxygen poisoning, acute inflammation, edema, autoimmune diseases, radiation diseases and other diseases are all related to the toxicity of active oxygen. Supplementing exogenous SOD is beneficial to delaying skin aging, resisting oxidation and removing pigmentation. Experiments show that SOD can eliminate free radicals, so it can eliminate the causes of the above diseases. This detoxification reaction process is divided into two steps:
The first step is: the harmful substance superoxide anion reacts with hydrogen ions under the action of SOD to generate another substance-hydrogen peroxide; In the second step, hydrogen peroxide reacts with hydrogen ions under the action of catalase, and finally produces a harmless substance-water.
The second step is: the human body removes the catalase or glutathione catalase produced in the first step, so the therapeutic effect will be better if the medicinal SOD as a therapeutic means is used in combination with catalase or glutathione catalase.
The mechanism and principle of SOD are as follows:
