Nitric Oxide overview by Dr. Louis Iganrro
What is Nitric Oxide – In common terms and despite being a simple molecule, nitric oxide (NO) is an important biological regulator and is therefore a fundamental component in the fields of neuroscience, physiology, and immunology. Watch this video to understand what role Nitric Oxide plays in your body.
What is Nitric Oxide?
Nitric oxide (nitrogen oxide, nitrogen monoxide) is a molecular, chemical compound with chemical formula of ·NO. One of several oxides of nitrogen, it is a colorless gas under standard conditions. Nitric oxide is a free radical—i.e., its bonding structure includes an unpaired electron, represented by the dot (·) on the nitrogen atom—and it is in the class of heteronuclear diatomic molecules that are of historic theoretical interest (for the insights they gave in formulating early modern theories of bonding).
It is a particularly important intermediate in the chemical industry. In addition, some is unavoidably produced during combustion of fossil fuels in power plants and automobile engines, with excess being created when more air or higher temperatures are present than needed for efficient and complete combustion of the fuel. It is also produced naturally by the extremely high air temperatures produced along the path of lightning in thunderstorms.
Dr. Louis J. Ignarro
Louis J. Ignarro (born May 31, 1941) is an American pharmacologist. For demonstrating the signaling properties of nitric oxide, he was co-recipient of the 1998 Nobel Prize in Physiology or Medicine with Robert F. Furchgott and Ferid Murad.
