free radical reactions

Free radical reactions involve highly reactive molecules called free radicals, which have unpaired electrons. These radicals seek to stabilize themselves by attaching to other molecules, often causing a chain reaction that can alter or damage substances. This process is common in processes like oxidation, aging, and certain chemical syntheses. Because free radicals can aggressively interact with stable molecules, their reactions can lead to structural changes, affecting materials and biological systems differently depending on context. Understanding these reactions helps in fields like biology, chemistry, and medicine, particularly in managing oxidative stress and developing antioxidants.
