Nitric oxide
Nitric oxide (NO) is a colorless gas that plays a crucial role in various biological processes. It is produced naturally in the body and acts as a signaling molecule, helping to regulate blood flow, immune response, and neurotransmission. NO is synthesized from the amino acid arginine by the enzyme nitric oxide synthase.
In addition to its biological functions, nitric oxide is also used in medicine. It can be administered to treat conditions like pulmonary hypertension and is involved in the development of certain medications. Its ability to relax blood vessels makes it important for cardiovascular health.
