The formation of superoxide ion radicals (${\mathrm{O}}_{\dot{2}}^{-}$) by chloroplasts from senescing leaves of Phaseolus vulgaris L. was determined by electron-spin-resonance measurements of Tiron ...

To investigate the effects of a traditional Chinese medicine formula Qing Huo Yi Hao (QHYH) and its components on hydroxyl radical (HO •) production in vitro and the activity of QHYH against free ...

Superoxide dismutase (SOD) genes encode a family of critical metalloenzymes that serve as a first line of defence against oxidative damage in plants. By converting the superoxide radical into less ...

Artificial enzymes made of treated charcoal could have the power to curtail damaging levels of superoxides, toxic radical oxygen ions that appear at high concentrations after an injury. Artificial ...

Free radicals are unstable atoms or molecules with free outer electrons. This makes them highly reactive because free electrons always strive to form a stable bond. This stabilization involves gaining ...

For organic chemists, the free-radical hydrostannylation of alkynes to produce vinylstannanes is a key step in important cross-coupling and other reactions. Every published mechanism has hinged solely ...
