What is free radicals?
Free radicals are active electrons. With blood circulation, it can attack the cell membranes, subcellular structures, nucleic acids and proteins of various organs, causing damage to target cells, leading to a series of unknown diseases. Free radicals can cause a variety of diseases, so scavenging free radicals is the fundamental way to prevent and treat many diseases. Free radical science has fully verified the theory of "same disease treatment" in the motherland. Formation and action of free radicals in human body: Oxygen free radicals are usually six oxidizing substances with high chemical reactions, namely superoxide anion radicals, hydroxyl radicals, hydrogen peroxide, singlet oxygen, nitric oxide and oxidative oxidation. Nitrogen. basis. Their chemistry is very active, and during normal metabolism, the body converts 2% of oxygen into negatively charged reactive oxygen (O2-) per day. However, cells also have a defense system for scavenging oxygen free radicals. Once the ability of oxygen free radicals to overproduce or scavenge oxygen free radicals in the body is reduced, or both, excess oxygen free radicals will cause cellular damage, known as oxidative stress. According to reports in the literature, billions of free radicals attack the human body about three thousand times a day. It can lead to peroxidation of cellular biofilms and inflammatory organelles, leading to structural and functional damage. The microsomal particles expand and deform, collapse, mitochondria agglutinate, lysosomal membrane fragility increases, permeability increases, and cell macromolecules such as nucleic acids, proteins and lipids can be destroyed. The formation of free radicals is formed by the oxidation of enzymes in the body. They can be seen in the human body at any time. They are free, active and active everywhere. Just like the oxidation and corrosion of metals, the harm of free radicals to the human body will not only increase. The human aging process can also trigger a range of diseases.
A series of internal and external causes can cause excessive free radicals in the body. External factors such as mobile phones, computers, air conditioners, electromagnetic radiation, ultraviolet rays, X-rays, automobile exhaust, industrial waste gas, waste water and other environmental pollution and residual pesticides and side effects of drugs, smoke, etc. may cause excessive free radicals. Intrinsic factors: excessive stress, such as excessive mental stimulation, excessive emotional changes, excessive work stress, overwork, excessive anger, nervousness, fear and other stress. Tissue organ damage, ischemia and embolic ischemia also produce excessive free radicals in the case of perfusion trauma, leading to the occurrence and development of diseases. Free radicals can cause serious damage to cells and tissues in the human body. Different organs and tissues can cause serious damage. Different organs of the human body are composed of different cells. Free radicals circulate into the bloodstream through blood pressure and are free in the blood. Alkali continues to accumulate, eroding various organ cells through blood circulation, causing damage to different cells and forming various diseases with the same factors and different diseases. The harmful effects of free radicals on the human body and the mechanism of free radicals have active chemical properties, which can react with organic matter in the cells and produce a large amount of peroxide in the body, causing the cells to lose normal physiological functions and cause corresponding diseases. There are three mechanisms: 1. Damage to the target cell membrane; 2. Inactivation of serum anti-protease; 3. Damage to the gene leads to cell variability.
The relationship between free radicals and disease
There is increasing evidence that oxygen free radicals play an important role in the development and progression of many human diseases, such as: arteriosclerosis, diabetes, hypertension, cardiovascular and cerebrovascular diseases, organ ischemia, ischemia-reperfusion injury, Tumors, senile dementia, aging, Parkinson's disease, cataracts, etc. In short, free radical accumulation leads to accelerated aging, and aging reduces the function of scavenging free radicals. Free radicals and aging are a vicious circle of human health. Therefore, many diseases can be called "free radical diseases." It can be seen that free radicals are inseparable from human life. Therefore, the elimination of free radicals has become an important measure of "anti-aging, disease resistance and life extension".
