WebAs proper aminoketyl radicals we denote the presumed intermediates of NCα bond dissociations induced by electron attachment to protonated peptides. These radicals have pyramidized aminoketyl groups, CαC (OH)NH, high spin density on the central carbon atom, and undergo facile NCα bond dissociations. The critical energies for NCα bond ...

The carbenium ions are stabilized by nucleophilic trapping or deprotonation to give compounds 14 and 18. Secondary alkyl and vinyl radicals are not oxidized and, in the absence of trapping reagents, form radical-derived products. WebRadical-induced cell death 1 (RCD1) also interacts with ANAC017 and is proposed to inhibit ANAC017 activity, potentially in an ROS-dependent manner 23. small telescopes are often advertised as
