What is free radical damage?
When oxygen reacts chemically with other atoms, interaction produces free radicals that are atoms containing non -saving electrorone in the outer shell. Unstable free radicals respond quickly with other compounds and try to steal electrorone. When the molecule loses its electron under the attack, it develops into a free radical itself and begins with a chain reaction. The main threat of free radicals comes from damage that causes cellular deoxyribonucleic acid (DNA) or cell membranes. Damage to free radicals that contribute to cancer, aging and many diseases can potentially prevent antioxidants that, as chemicals that easily donate electrons, free radicals. Oxygen occupies the final position in the electron transport chain and the defective interaction between electron and oxygen creates a radical form of oxygen, the more -running free radical in living systems. The primary mechanism of damage to radical oxygen in the cell is the cell DNA mutation. While the mechanisms of repair in the cell can be egAvit nuclear DNA, mitochondrial DNA (MTDNA) cannot be easily restored. The accumulative damage to MTDNA accumulates over time, resulting in extensive mitochondrial dysfunction, decreased cells and final cell death.
changes in the source of the source with sunlight create other free radicals. In the lower atmosphere, the most important examples of nitrogen dissociation are induced by light, providing oxygen and nitric oxide, a key component in smog and ozone photodisocation to develop an excited oxygen atom. An important source of radicals is the dissociation of chlorofluorocarbones either by ultraviolet radiation or by reactions with other stratospheric ingredients. These free radicals are destroyed by Ozon Layer.
Damage damage to DNA radicals leads to mutations that cause malignancy. Atherosclerosis, liver damage related to alcohol and cigarette smoking are attributed to oxidation of many body chemicals inducedfreely radical. Free radicals can cause schizophrenia, Alzheimer's disease, Parkinson's disease and deafness. Another example of free radical damage is skin damage that occurs with excessive exposure to the sun. "The theory of aging free radicals" suggests that free radicals start the process of aging.
Oxidation is the process of damage to free radicals caused by radical oxygen. Antioxidants are molecules that can safely donate electrons to free radicals, ending the reaction of the oxidation chain before damage to critical molecules. Although several enzyme systems in the bodies capture free radicals, the main vitamin or mineral antioxidants include vitamin A or beta-carotene, vitamin E, vitamin C and selenium, which is a trace metal.
