Free radicals are molecules with an unpaired electron. The extra electron makes them unstable and in order to stabilize themselves, these molecules will "steal" an electron from other healthy molecules. This process triggers a chain reaction that eventually results in damaged DNA. Free radicals are found everywhere, but external factors like pollution and sunlight trigger the production of more of these molecules. Antioxidants help stop free radical damage by accepting or donating an electron to make it stable.
