full_question: Nitroso containing compounds are used for analyzing these compounds by extending their lifetimes through the formation of a stable adduct. The previously mentioned spin-trap compounds are commonly used in E-S-R, which can detect these compounds due to their paramagnetism. Fishhook arrows often appear in reaction mechanisms involving these compounds, such as during homolytic cleavage. Glutathione ["glue-ta-THY-own"], superoxide dismutase, and vitamin C prevent the formation of these compounds, which Denham Harman proposed caused aging. For 10 points, name these reactive molecules which contain unpaired electrons and which are suppressed by antioxidants.
