The electron adduct of disulfide RSSR<sup>.-</sup> has been proved to be a critical intermediate of the disruption of the disulfide bridge that leads to the inactivation of enzymes. However, the transient radicals produced by the radiation oxidation of cystine, such as CySSCy<sup>+</sup>, CySS, can also make inactive enzymes.展开更多

The cation radical of C60 is produced either via hole transfer from cation radical of CCl4 to C60 or via electron transfer from excited triplet of C60 to CCl4. C60 and C70 could be added to trichloromethyl radical to produce adduct radicals with different mechanisms.展开更多
