The ultimate precursor of the carbonate radical anion being bicarbonate, carbon dioxide, peroxymonocarbonate or complexes of transition metal ions with bicarbonate-derived species remains a matter of debate. The carbonate radical has also been proposed to be responsible for the stimulatory effects of the bicarbonate-carbon dioxide pair on oxidations mediated by hydrogen peroxide/transition metal ions. The bicarbonate-carbon dioxide pair stimulates the oxidation, peroxidation and nitration of several biological targets. Bicarbonate in equilibrium with carbon dioxide constitutes the main physiological buffer in cells. The carbonate radical is an elusive and strong one-electron oxidant. The bicarbonate ion carries a negative one formal charge and is the conjugate base of carbonic acid, H2CO3. It is an anion that consists of one central carbon atom surrounded by three oxygen atoms in a trigonal planar arrangement, with a hydrogen atom attached to one of the oxygens. Bicarbonate is a simple single carbon molecule that plays surprisingly important roles in diverse biological processes.
