what element makes nitric oxide in body
âWeâve focused for many years on the nitric oxide pathway to find new therapies that might improve outcomes for babies with pulmonary hypertension,â Aschner said. In the body, the enzyme nitric oxide synthase (NOS) produces nitric oxide from the amino acid arginine. Aschner and colleagues had discovered that NOS is present in a multi-protein complex, which is important for the activation of NOS and production of nitric oxide.
