They readily participate in chemical reactions to achieve a stable electron configuration, often by stealing an electron from another molecule.
Free radicals are generated through various processes, both natural and artificial. In biological systems, they are
While essential for some physiological functions, such as immune responses and cell signaling, an excessive accumulation
The body has natural defense mechanisms against free radicals in the form of antioxidants. Antioxidants are
