Free radical injury
Free radicals are highly reactive chemical entities with unpaired electrons that can be toxic under some conditions. There are several types of free radicals including oxygen, sulfur, carbon, and nitrogen centered radicals. Free radicals are formed by either losing or gaining a single electron from a non-radical species and play a role in oxidative stress through reactions like the Fenton reaction.
