neuronal nitric oxide synthase

Neuronal nitric oxide synthase (nNOS) is an enzyme found in nerve cells that produces nitric oxide, a small signaling molecule. Nitric oxide helps in communication between neurons, regulating blood flow, and supporting various brain functions like learning and memory. When activated, nNOS converts amino acids into nitric oxide, which quickly influences nearby cells. This process is essential for normal nervous system activity, but excess production can lead to issues like neuroinflammation or damage. Overall, nNOS plays a key role in maintaining healthy neural communication and blood flow regulation in the brain.
