In conditions where zinc is deficient, the NADPH oxidase enzymes and nitric oxide synthase are activated, favoring the production of reactive species of oxygen and nitrogen. On the other hand, zinc also acts as a pro-oxidant when its concentration is either deficient or in excess and becomes pro-inflammatory and pro-apoptotic.
