Nitric Oxide vs. Nitrous Oxide: What's the Difference?

Edited by Sawaira Riaz || By Sumera Saeed || Updated on November 28, 2023
Nitric oxide (NO) is a simple gaseous signaling molecule; nitrous oxide (N2O) is a gas used for anesthesia and as a propellant.

Key Differences

Nitric oxide, with the chemical formula NO, is a free radical molecule which plays crucial roles in various physiological processes, including vasodilation, immune system modulation, and neurotransmission. On the other hand, nitrous oxide, having the chemical formula N2O, is primarily known for its application in medicine as an anesthetic, as well as its recreational use as a "laughing gas".
