Evidence suggests that pumping in too much oxygen too quickly can strip the molecule of a single electron, creating a free radical.

证据显示，太快地吸入过多的氧气可能夺走单电子的分子，形成自由基。

During the reperfusion period, endothelial dysfunction, activation of endogenous enzymes, leucocyte recruitment and activation all lead to the generation of oxygen -derived free radical.

再灌注期间，上皮细胞功能障碍，内源酶激活，白细胞聚集并活化，都会导致氧自由基的产生。

Blueberry and Bilberry are ranked as some of the highest antioxidant rich fruits based on their ability to scavenge oxygen free radicals in the ORAC (oxygen radical absorbance capacity) test.

蓝莓与山桑子经过“氧自由基吸收能力分析(ORAC)”测试，被评等为富含抗氧化能力最高等级的果实，具有清除氧化自由基的特性。

Eliminating free radical production would involve completely redesigning aspects of our metabolism, especially the way we use oxygen to extract energy from food.
