Mechanism Of Action Of Vitamin C As Antioxidant
Vitamin C, also known as ascorbic acid, is a potent antioxidant that helps protect the body against free radicals. Free radicals are unstable molecules that can damage cells and contribute to the development of various diseases, including cancer and heart disease. The mechanism of action of vitamin C as an antioxidant is complex, but it basically involves neutralizing free radicals and preventing them from causing harm.
What are antioxidants?
Antioxidants are molecules that neutralize free radicals by donating an electron to them. Free radicals are unstable molecules that are missing an electron, which makes them highly reactive and capable of damaging cells. Antioxidants can donate an electron to a free radical without becoming unstable themselves, thus preventing the free radical from causing damage.
How does vitamin C act as an antioxidant?
Vitamin C acts as an antioxidant by donating an electron to free radicals, thereby neutralizing them. However, this process is not as simple as it seems. Vitamin C can donate an electron to a free radical only once, after which it becomes unstable and reactive. To prevent this, vitamin C can react with other antioxidants, such as vitamin E, to form a stable molecule. This process is known as regeneration and helps maintain the antioxidant capacity of vitamin C.
What are the benefits of vitamin C as an antioxidant?
Vitamin C offers several benefits as an antioxidant, including:
- Reducing the risk of chronic diseases, such as cancer and heart disease
- Protecting the skin against UV damage and aging
- Boosting the immune system
- Reducing inflammation
How much vitamin C do you need?
The recommended daily intake of vitamin C is 75-90 milligrams for adults. However, smokers, pregnant women, and people with certain medical conditions may require higher amounts. It is best to get vitamin C from food sources, such as citrus fruits, kiwi, strawberries, and broccoli, rather than supplements.
Conclusion
Vitamin C is a powerful antioxidant that helps protect the body against free radicals. Its mechanism of action involves neutralizing free radicals and preventing them from causing harm. Vitamin C offers several benefits as an antioxidant, including reducing the risk of chronic diseases, protecting the skin, boosting the immune system, and reducing inflammation. It is important to get enough vitamin C from food sources to maintain optimal health.
