Chemists and biologists define '''oxidative stress''' as an imbalance, in particular in a biological system, between oxidative factors and antioxidant protective factors, the imbalance characterized by an excess of the former or a deficiency of the latter.
Chemists and biologists often define '''oxidative stress''' as an imbalance, in particular in biological cells, between the rate of formation and/or concentration oxygen free radicals — potent 'oxidizing' (electron capturing) molecules — and their elimination or 'neutralization' by antioxidants — 'reducing' (electron donating) molecules — the imbalance characterized by an excess of the former or a deficiency of the latter, leading to an alteration of a cell's redox state towards the oxidized state.
