Oxidizing potential

A disulfide bond is a sulfur-sulfur bond, usually formed from two free thiol groups. The interconversion between dithiol and disulfide groups is a redox reaction: the free dithiol form is in the reduced state, and the disulfide form is in the oxidized state. Notice that in the oxidized (disulfide) state, each sulfur atom has lost a bond to ...

OXIDATION Oxidation is the loss of electrons by an atom, mole-cule, or ion. It may or may not be accompanied by the addition of oxygen, which is the origin of the term.Oxidizing Agents. If one reagent in a reaction contributes oxygen, extracts hydrogen, or extracts electrons, it is said to be an oxidizing agent. Of course, it is reduced in the process. Since oxidation and reduction are symmetric processes, always occurring together, there is always an oxidizing agent and a reducing agent in the reaction.12.7: Oxidizing Agents.
