Free radicals are constantly formed in the human body, both by "accidents of chemistry" and for useful metabolic purposes. Their action is opposed by a balanced and co-ordinated system of antioxidant defences. Upsetting this balance causes oxidative stress, which can lead to cell injury and death.
自由基在人体内持续产生,既源于“化学意外”,也出于有益的代谢目的。它们的作用会受到一个平衡且协调的抗氧化防御系统的对抗。打破这种平衡会导致氧化应激,进而可能引发细胞损伤和死亡。
