脂过氧化作用是指在不饱和脂肪酸中发生的一系列自由基反应。这种作用可用来解释或部分解释某些疾病发生的原因及病理过程,如化学中毒、大气污染毒害、辐射损伤、化学致癌、肌肉萎缩、溶血性贫血和动脉粥样硬化等,它还与一些正常的生理过程,如前列腺素合成、吞噬作用和衰老等有关。近几年来,随着膜类脂化学的发展,脂过氧化作用造成的损伤及其生理学意义,越来越引起生物学和医学工作者的注
Lipid peroxidation refers to a series of free radical reactions that occur in unsaturated fatty acids. This role can be used to explain or partly explain the causes of certain diseases and their pathological processes such as chemical poisoning, air pollution poisoning, radiation damage, chemical carcinogenesis, muscle atrophy, hemolytic anemia and atherosclerosis, Normal physiological processes, such as prostaglandin synthesis, phagocytosis and aging and so on. In recent years, with the development of membrane lipid chemistry, the damage caused by lipid peroxidation and its physiological significance have increasingly drawn the attention of biologists and medical workers
