SUMMARY

Nitric Oxide (NO) is produced in higher organisms by the oxidation of one of the terminal guanido-nitrogen atoms of L-arginine. Nitric Oxide Synthase (NOS) catalyzes the oxidation of arginine to NO and citrulline. Reduced nicotinamide adenine dinucleotide phosphate (NADPH) and oxygen (O2) are required as co-substrates.

NOS exists in three distinct isoforms: 1. constitutive neuronal NOS (NOS I or nNOS), 2. inducible NOS (NOS II or

iNOS), and 3. constitutive endothelial NOS (NOS III… Continue reading
