摘要
活性氧是机体正常的代谢产物,但其存在具有两面性。天然抗氧化剂作为机体抗氧化非酶系统的成分,除可直接清除活性氧,还可抑制活性氧的产生;或通过作用于抗氧化反应元件而提高内源性抗氧化物质的水平或抑制氧化酶的表达而减少ROS的产生。不同抗氧化剂在行使抗氧化作用时往往具有协同增效作用。
Reactive oxygen species is the normal metabolic products of organism,but the existing of it has two sides.Natural antioxidant,as the component of the body＇s antioxidant non-enzymatic system,it can not only eliminates reactive oxygen species directly,but also can restrains the producing of reactive oxygen species or enhances the level of endogenous antioxidative substances through interacting on the antioxidant response element,or inhibits the expression of antioxidant enzyme to reduce the producing of ROS.Generally,different antioxidants have synergistic effects when exercising it＇s antioxidation.
