An acid radical is an anion left after removal of hydrogen cation from an acid, for example NO3 and SO4. The enzyme cytochrome c oxidase, EC 188.8.131.52) is a large transmembrane protein complex found in bacteria and the mitochondrion. It is the last enzyme in the respiratory electron transport chain of mitochondria located in the mitochondrial membrane. It receives an electron from each of four cytochrome c molecules, and transfers them to one oxygen molecule, converting molecular ...

The semiquinoid ascorbic acid radical is a strong acid (pKa −0.45); after the loss of a proton, it becomes a radical anion that, owing to resonance stabilization, is relatively inert but disproportionates to ascorbic acid and dehydroascorbic acid. Thus, the three forms (ascorbic acid, semidehydroascorbic acid, and dehydroascorbic acid) compose a reversible redox system. Thus, it is an effective quencher of free radicals such as singlet oxygen (1O2). It reduces ferric (Fe3+) to ferrous (Fe2+) ...
NHR, and the prototype imidic acid radical cation, HN=C(H)OH + , ionized formimidic acid, has been generated by an appropriate dissociative ionization and identified by CID type experiments. Neutral imidic acids have been proposed as intermediates in the acid-catalysed proton exchange of amides, peptides and proteins, a process of fundamental importance in biochemistry (eqn  as opposed to the ...
