Nitric oxide

Introduction: Nitric oxide

Description of Nitric oxide

Nitric oxide: Nitric oxide (NO) is a small, soluble, diffusible, highly reactive gas molecule, which is critical to numerous biological processes, including vasodilation, neurotransmission and macrophage-mediated microorganism and tumor killing. NO often plays a role of a biological signal. It is involved in neuron to neuron signaling, and probably contributes to the formation of memories. Most non-pathological functions of NO are mediated by activation of guanylyl cyclase, or by nitrosylation of proteins. NO can also inhibit oxygen consumption by mitochondria. (NCI)

Nitric oxide: NO; originally found as an intercellular messenger molecule in vascular smooth muscle, where it has a relaxant, vasodilatory effect; formed by oxidation of arginine with citrulline as side product; in nervous tissue, may be part of glutamate-calcium-cGMP signal transduction system.

Nitric oxide: A free radical gas produced endogenously by a variety of mammalian cells, synthesized from ARGININE by NITRIC OXIDE SYNTHASE. Nitric oxide is one of the ENDOTHELIUM-DEPENDENT RELAXING FACTORS released by the vascular endothelium and mediates VASODILATION. It also inhibits platelet aggregation, induces disaggregation of aggregated platelets, and inhibits platelet adhesion to the vascular endothelium. Nitric oxide activates cytosolic GUANYLATE CYCLASE and thus elevates intracellular levels of CYCLIC GMP.
