Nitrosylation results in a molecule "R" adducted with the group N=O

Nitrosylation is the general term for covalent incorporation of a nitric oxide "nitrosyl" moiety into another (usually organic) molecule. There are multiple chemical mechanisms by which this can be achieved; including biological enzymes and industrial processes. The biological functions of nitrosylation are particularly important as S-nitrosylation, the conjugation of NO to cysteine thiols in proteins, is an important part of cell signalling.[1] Coordination of NO to transition metals to give metal nitrosyl complexes, is also referred to as nitrosylation.[2]
