Question

Nitric oxide is synthesized from​

Answer 1

Answer:

Amino Acid l-arginine.

Nitric oxide (NO), synthesized from the amino acid l-arginine by NO synthases, is a unique type of transmitter in the nervous system.

Explanation:

Nitric oxide is produced by a group of enzymes called nitric oxide synthases. These enzymes convert arginine into citrulline, producing NO in the process. Oxygen and NADPH are necessary co-factors. The isoforms of NOS are neuronal NOS (or nNOS), endothelial NOS (or eNOS) and inducible NOS (or iNOS).
