生物氧化不仅为机体提供能量,在氧化过程中也产生与氧有关的超氧离子O_2~-自由基和羟自由基·OH等。这些自由基可激发机体中不饱和脂肪酸邻近双键α-碳上的氢键均裂,形成一系列自由基反应,称之谓脂质过氧化作用。近几年来关于脂质过氧化作用的研究涉及面相当广泛,包括某些疾病的病理过程如肿瘤、感染、炎症反应、自身免疫病、化学中毒、辐射损伤及 Biooxidation not only provides energy for the body, but also produces oxygen-related oxygen ions O 2 - and hydroxyl radical · OH in the oxidation process. These free radicals can stimulate the unsaturated fatty acids in the body adjacent to the double bond on the α-carbon hydrogen bonds are split, the formation of a series of free radical reactions, called lipid peroxidation. In recent years, the research on lipid peroxidation involves a wide range of aspects, including the pathological processes of certain diseases such as cancer, infection, inflammation, autoimmune diseases, chemical poisoning, radiation damage and
