Résumé
Selenium, an essential micronutrient is being thoroughly investigated for its role in the catalytic cycle of oxidoreductase enzyme like glutathione peroxidase (GPx) and in combating oxidative stress in cells. The protective ability of selenium compounds against oxidative assault has been found to be superior as compared to its lighter analogue, sulfur. In the presentation, a few examples from our studies depicting the role of physico-chemical properties of functionalized selenoether and thioether responsible for their differential reactivity will be discussed. The studies have been carried out with hydroxyl (●OH) radical, using nanosecond pulse radiolysis coupled with absorption detection...
