Unraveling the reactions of nitric oxide, nitrite, and hemoglobin in physiology and therapeutics. Nitric oxide (NO), a free radical signalling molecule is synthesized endogenously from l ‐arginine and molecular oxygen in a reaction catalysed by the enzyme NO synthase (NOS). High intensity interval training (at 85% to 90% of VO2max) is more effective in improving endothelial function and nitric oxide availability than continuous moderate aerobic exercise. In this process the cofactors: NADPH, O 2 , BH 4 , FMN, FAD are used in addition to the nitric oxide synthase enzyme in order to help catalyze (start/process) this reaction. But nitric oxide production decreases with age.
