nitric oxide

n.
A colorless, poisonous gas, NO, produced by the partial oxidation of atmospheric nitrogen, by cellular metabolism, and as an intermediate during the manufacture of nitric acid from ammonia. In the body, nitric oxide is involved in oxygen transport to the tissues, the transmission of nerve impulses, and other physiological activities.
