Which enzyme reduces free radicals?
Superoxide Dismutases (SOD). These enzymes have either a manganese, copper, or zinc cofactor, which is essential for their free radical detoxifying activity. During SOD-mediated enzymatic catalysis, two superoxides are converted into hydrogen peroxide and oxygen.
How can we reduce free radicals naturally?
Keep in mind that free radical content is high in nutrient-poor meals and those deficient of antioxidants.
- Avoid high glycemic foods, or foods that are rich in refined carbohydrates and sugars.
- Limit processed meats such as sausages, bacon and salami.
- Limit red meat.
- Don’t reuse cooking fats and oils.
- Limit alcohol.
Do free radicals affect enzymes?
[26] Free radical mediated protein modification increases susceptibility to enzyme proteolysis. Oxidative damage to protein products may affect the activity of enzymes, receptors, and membrane transport.
What neutralizes free radicals in the body?
Antioxidants
Antioxidants are chemicals that interact with and neutralize free radicals, thus preventing them from causing damage. Antioxidants are also known as “free radical scavengers.” The body makes some of the antioxidants that it uses to neutralize free radicals. These antioxidants are called endogenous antioxidants.
What are enzymatic antioxidants?
Enzymatic antioxidants work by breaking down and removing free radicals. The antioxidant enzymes convert dangerous oxidative products to hydrogen peroxide (H2O2) and then to water, in a multi-step process in presence of cofactors such as copper, zinc, manganese, and iron.
Which vitamin protects cells from free radicals?
vitamins C and E
Antioxidants, such as vitamins C and E and carotenoids, may help protect cells from damage caused by free radicals.

What are some natural antioxidants?
Sources of antioxidants
- allium sulphur compounds – leeks, onions and garlic.
- anthocyanins – eggplant, grapes and berries.
- beta-carotene – pumpkin, mangoes, apricots, carrots, spinach and parsley.
- catechins – red wine and tea.
- copper – seafood, lean meat, milk and nuts.
- cryptoxanthins – red capsicum, pumpkin and mangoes.
What are antioxidants and free radicals?
Antioxidants are nutrients that help minimize free-radical damage to the body. Free radicals are highly reactive compounds that are created in the body during normal metabolic functions or introduced from the environment, such as by exposure to pollution and other toxins.
Which vitamin is the strongest antioxidant?
Vitamin C, commonly known as ascorbic acid, is the most powerful water-soluble antioxidant found in blood plasma.
