Antioxidant State (null)

The term "Antioxidant state" does not refer to a single molecule or receptor but rather describes the collective ability of cells and tissues to counteract oxidative damage caused by reactive oxygen species and free radicals. This protective function involves both enzymatic systems—such as superoxide dismutase, catalase, and peroxidases—and non-enzymatic molecules like glutathione, vitamins C and E. The antioxidant state reflects the balance between pro-oxidants and antioxidants within biological systems. Imbalances can lead to oxidative stress associated with various diseases including cancer, cardiovascular disorders, neurodegenerative conditions such as Alzheimer's disease and Parkinson's disease. Measurement methods include assays for total antioxidant capacity such as ORAC.
