oxidationsskydd

Oxidationsskydd, often translated as antioxidant, refers to a substance that inhibits oxidation. Oxidation is a chemical reaction that can produce free radicals, leading to chain reactions that may damage cells. Oxidationsskydd terminate these chain reactions by reacting with free radicals, and thus preventing or slowing down the oxidative damage. These compounds can be synthetic or naturally occurring.

In biological systems, oxidative stress is implicated in various diseases and aging processes. Therefore, many foods and dietary supplements contain oxidationsskydd to combat this. Common dietary oxidationsskydd include vitamins like vitamin C (ascorbic acid) and vitamin E (tocopherol), as well as minerals such as selenium. Other well-known examples include carotenoids like beta-carotene and polyphenols found in fruits, vegetables, and beverages like tea and red wine.

Industrially, oxidationsskydd are used to protect materials from degradation. For instance, they are added to plastics, rubber, and fuels to extend their lifespan by preventing oxidation caused by exposure to air and heat. The mechanism of action for these industrial oxidationsskydd is often similar to their biological counterparts, involving the scavenging of free radicals that initiate degradation processes. The effectiveness of an oxidationsskydd depends on its chemical structure and its ability to interact with specific oxidizing agents or free radicals.
