By stabilizing these free radicals antioxidants can also help your immune system function more efficiently and mitigate chronic inflammation which is thought to be a driving force for many health.
In the case of a weakening of such an antioxidant defence or excess production of radicals a state of oxidative stress occurs. Indeed a group of Russian microbiologists discovered that CO2 at a tension close to that observed in the blood 370 mm Hg and high tensions 60 or 146 mm Hg is a potent inhibitor of generation of the active oxygen forms free radicals by the cells and mitochondria of the. They may reduce the energy of the free radical stop the free radical from forming in the first place or interrupt an oxidizing chain reaction to minimize the damage caused by free radicals.
This helps break a chain reaction that can affect other molecules in the cell and other cells in the body. These antioxidants or free radical scavengers include ascorbic acid vitamin C alpha-tocopherol vitamin E beta-carotene coenzyme Q10 enzymes such as catalase and superoxide dismutase and. Peroxyl radical initiates a chain reaction and transforms polyunsaturated fatty.
Antioxidants neutralize free radicals by donating one of their own electrons ending the electron-stealing reaction. This helps break a chain reaction that can affect other molecules in the cell and other cells in the body. Antioxidants stop the chain reaction of free radical formation and benefit our health by.
Non-enzymatic antioxidants such as vitamin E interrupt the chain reaction and prevent further damage. In making this sacrifice they act as a natural off switch for the free radicals. If free radicals continually build up in our body this begins a process called Oxidative Stress.

Free radicals can trigger lipid peroxidation chain reactions by abstracting a hydrogen atom from a side-chain methylene carbon. Normal arterial levels of CO2 have antioxidant properties. Oxidative stress can do major damage to the bodys cells leading to disease and the aging process in general.
Free radical detoxifying enzyme systems are responsible for protecting the insides of cells from free radical damage. Although some free radicals are produced naturally in the body youre hear to learn how antioxidants reduce free radicals. Vitamins C and E are considered antioxidants in addition to their many other valuable functions.
Antioxidants neutralize free radicals either by providing the extra electron needed to make the pair or by breaking down the free radical molecule to render it harmless. Antioxidants combat free radicals in several ways. Humans are well endowed with antioxidant defences against AOS.
