oxygen-derived free radicals |
| 释义 |
oxygen-derived free radicals ox·y·gen-de·rived free rad·i·calsan atom or atom group having an unpaired electron on an oxygen atom, typically derived from molecular oxygen. For example, 1-electron reduction of O2 produces the superoxide radical, Ō2·; other examples include the hydroperoxyl radical (HOO·), the hydroxyl radical (HO·), and nitric oxide (NO·). These apparently have a role in reprofusion injury.ox·y·gen-de·rived free rad·i·cals (ok'si-jĕn dĕ-rīved' frē rad'i-kălz) An atom or atom group having an unpaired electron on an oxygen atom, typically derived from molecular oxygen.
