[110] These enzymes share the same basic catalytic mechanism, in which a redox-active cysteine (the peroxidatic cysteine) in the active site is oxidized to a sulfenic acid by the peroxide substrate. [62] Uric acid's antioxidant activities are also complex, given that it does not react with some oxidants, such as superoxide, but does act against peroxynitrite,[63] peroxides, and hypochlorous acid. Here are a few examples: The other trace minerals perform equally vital jobs, such as helping to block damage to body cells and forming parts of key enzymes or enhancing their activity. Ultimately, more research is needed in humans. Health enthusiasts have long raved about the countless benefits of wheatgrass, and for good reason. Consuming them on a regular basis may help reduce many risk factors for heart disease, including high blood pressure, high cholesterol, elevated triglyceride levels, and obesity (7, 8). Adding black tea to your daily routine is an easy way to incorporate antioxidants into your diet and potentially reduce your risk of future health complications.
