Iron free radical
WebFree radicals, intermediates in the tissue damage caused by radiation, are formed,inter alia, in interactions catalyzed by iron, which synergizes with radiation and some cytostatics … WebA free radical is an atom, molecule, or compound that is highly unstable because of its atomic or molecular structure (i.e., the distribution of electrons within the molecule). As a result, free radicals are very reactive as they attempt to pair up with other molecules, atoms, or even individual electrons to create a stable compound.
