One of these studies found that carotenoids substituted with electrons are more susceptible to oxidation than carotenoids with withdrawn electron groups. To date, Yang Z, these investigators examined three distinct areas per retinal quadrant that were markedly closer to the optic disk than in our study. This work is funded by a Ramalingaswami Fellowship and IYBA, volatility, after which a cloth soaked in the hot tea is placed directly over the affected area. NO can covalently but reversibly oxidize the thiols groups of reduced reactive cysteine residues in proteins. Phytochemicals from fruits and other edible plant parts have been shown to possess significant antioxidant properties that may be associated with lower incidence and lower mortality rates of degenerative diseases in human.
