WebNitric Oxide Nitric oxide (NO), is a free radical gas that is a powerful regulator of circulation (it is an endogenous vasodilator) and a neurotransmitter (it helps in the processing of nerve signals as they cross synapses). L-arginine, one of 20 amino acids that make up proteins, is the only amino acid that generates significant amounts of NO. Web1 jan. 1994 · Hemoglobin, along with related hemoproteins such as myoglobin, can be used for the measurement of nitric oxide (NO). The technique is based on the direct reaction between NO and the oxygenated, ferrous form of hemoglobin (HbO 2 ), which yields the ferric form, methemoglobin (metHb), and nitrate.
