Reactive Nitrogen Species Nitric Oxide

l-arginine (l-Arg) along with the molecular oxygen forms nitric oxide (NO) and citrulline and this reaction is catalyzed by nitric oxide synthase. NO also has a role in cell and tissue destruction, sterile inflammation, and formation of adhesions [21]. The two common examples of reactive nitrogen species are nitric oxide (NO) and nitrogen dioxide [22, 23]. NO is involved in the regulation of various physiological processes and is proven to be toxic if present in excess levels [21, 22, 24]. The actions of NO in a cell depend on its concentration, the cellular redox state, and the abundance of metals, protein thiols and low-molecular weight thiols (glutathi-one) as well as other nucleophil targets [25]. High levels of nitric oxide (NO) alter both motility and sperm competence for zona binding [4] .
