Reactive To Cellular Structures: Free Radicals

Satisfactory Essays
Free radicals are molecules that are very reactive to cellular structures because they have unpaired electrons. Free radicals naturally develop from biological reactions in the body - immune system responses, like when your body fights off sickness, or metabolic processes, such as breaking down glucose. Free radicals can be found almost anywhere; medicine, food, air. Some things nearly guaranteed to contain it would be fried food, tobacco, alcohol, pollutants from the air.
