近年来,自由基(free radical)在生物体系中的作用已成为一个非常活跃的研究领域。诸如生物氧化、光合作用、细胞作用、细胞增殖、机体衰老、炎症、肿瘤、血液病、动脉粥样硬化、幅射损伤以及环境污染等方面,均有人通过研究自由基反应探讨其机理。在病理情况下,自由基具有强大的破坏作用。可使核酸主链断裂,碱基降解和 In recent years, the role of free radicals in biological systems has become a very active area of ​​research. Some people, such as bio-oxidation, photosynthesis, cell function, cell proliferation, body aging, inflammation, cancer, blood diseases, atherosclerosis, radiation damage and environmental pollution, In the case of pathology, free radicals have a powerful damaging effect. Can break the nucleic acid backbone, base degradation and
