To mimic the structure and function of nitric-oxide reductase, the researchers began with myoglobin, a small muscle protein.

Reversible and Ultrasensitive Detection of Nitric Oxide Using a Conductive Two‐Dimensional Metal–Organic Framework. Angewandte Chemie International Edition , 2024; DOI: 10.1002/anie.202419869 ...

This comprehensive review maps natural nitrite reductases and synthetic mimics that enable on-demand nitric oxide ...

But when nitric oxide binds to the iron in myoglobin, it stabilizes the iron and creates an antioxidant effect. That, along with the added salt from the curing agent, creates new flavors in the meat.

Nitric oxide therapy has been in use for many years and is considered safe. Still, it’s natural that you may have questions about how it works or what to expect. Questions for your doctor.
