WebJun 7, 2024 · Introduction. As a transition metal, copper (Cu) plays several key roles in the human body. These various roles are due to its two oxidation states, Cu (I)/Cu + (cuprous ion) and Cu (II)/Cu 2+ (cupric ion), which endow it with the ability to act as either a recipient or a donor of electrons. Cu + prefers to bind to the thiol group in cysteine ...
