radikalfänger

Radikalfänger is a German term that translates to "radical catcher" or "radical scavenger" in English. It refers to a substance that can neutralize or react with free radicals. Free radicals are highly reactive molecules that have an unpaired electron, making them unstable and prone to damaging other molecules in a process called oxidation. This oxidative damage is implicated in aging and various diseases, including cancer and cardiovascular disorders.

Antioxidants are the most common type of radikalfänger. They work by donating an electron to the free radical, thereby stabilizing it and preventing it from causing further harm. This sacrificial action of the antioxidant molecule effectively "catches" or "scavenges" the damaging radical.

The body naturally produces some radikalfänger, such as enzymes like superoxide dismutase and glutathione peroxidase. However, dietary intake of antioxidants is also crucial. Many foods, particularly fruits, vegetables, and whole grains, are rich in various antioxidant compounds like vitamins C and E, carotenoids, and polyphenols. These dietary antioxidants play a significant role in protecting cells from oxidative stress.

In industrial applications, radikalfänger are used to prevent degradation of materials like plastics, rubber, and oils, which can be damaged by free radicals generated by heat, light, or oxygen. These industrial antioxidants extend the lifespan and maintain the properties of these materials.
