Nitric Oxide - Neurotransmitter - Blood Vessel Dilator

Nitric Oxide (NO)

- Blood vessel dilator

Dubbed "Molecule of the Year" by Science magazine in 1992

Nitric oxide (NO) is NOT the same as nitrous oxide (N2O, better known as laughing gas)

What is NO?

1 nitrogen atom + 1 oxygen atom

Soluble, highly reactive, short-lived gas

Production pathways:

–   Produced in certain animal and plant cells from the amino acid L-arginine

Arginine –Precursor to blood vessel dilator Nitric Oxide

–   Can be derived from nitroglycerine - well known as a major component of dynamite, but also prescribed in the medical field, E.g. as a nitroglycerine patch. Ironically, Alfred Nobel, the founder of the Nobel Prize,invented dynamite, but did not follow his doctor's advice to take a compound that signals nitric oxide release for his heart health. It wasn't until ~ 100 years later it was more fully realized how such products act by releasing nitric oxide gas as a signal molecule.

–   A byproduct of combustion - also a product of natural chemical reactions in the atmosphere.

NO has many roles

NO operates as a signaling molecule(neurotransmitter) in brain and immune system - NOsignaling efficiency declines with age.

NO enhances blood flow and helps maintain optimal blood pressure

–   The 1998 Nobel Prize winners(Furchgott, Murid, and Ignarro)discovered how endothelial cells produce NO gas to help blood vessels stay relaxed and open for blood flowthese cells lining the blood vessels require the semi-essential amino acid Arginine as a precursor for producing NO

Arginine –Precursor to blood vessel dilator Nitric Oxide

✔ Improves all physiological processes by improving both nutrient delivery to cells and cellular waste removal

✔ NO also helps promote healthy blood vessel flexibility and dilation - as a cellular signaling molecule

✔ Sufficient NO reduces risk for coronary artery disease (CAD) - by helping keep arteries stay more plaque-free

✔ Good blood flow Important in maintaining an erection
