About

Nitric oxide (NO) is a fascinating molecule that plays a crucial role in both biological processes and atmospheric chemistry. This colorless gas consists of one nitrogen atom and one oxygen atom joined by a bond that gives the molecule some remarkable properties. What makes nitric oxide particularly interesting is its dual nature in biological systems – while it’s an essential signaling molecule in the human body, helping to regulate blood pressure and nerve function, it can also be quite reactive and potentially harmful in high concentrations. The molecule’s unpaired electron makes it a free radical, giving it a relatively short half-life and high reactivity with other molecules.

Understanding nitric oxide’s behavior has led to important medical breakthroughs, including treatments for heart disease and the development of medications like nitroglycerin for angina.
