He was fascinated that the colorless, odorless gas could act as a signaling molecule. nitric oxide6. Dr Furchgott, 82, said he was mildly surprised to have won the Nobel prize because most such prizes go to more popular areas, such as molecular research. 2.. Nitric oxide synthaseMany reports supported the idea that mammalian cells synthesize nitric oxide (Ignarro et al., 1987, Palmer et al., 1987).In 1989 it was reported that endothelial cells contain a cytosolic enzyme which is either directly or indirectly regulated by Ca 2+, and which converts l-arginine into a compound which stimulates sGC and behaves similarly to EDRF (Mayer et al., 1989). Nitric oxide is a very important molecule in the human body, that is severely depleted after the age of 40. It’s responsible for regulating blood flow, blood pressure, it’s produced by our white blood cells in the immune system to fight off infections, and it’s a neurotransmitter in the central nervous system. His work, done independently and together with that of Dr Furchgott, prompted an increase in research activities in many areas of the world.
