- •
Nitrosyl hemochromogen (NO-Heme) is extremely unstable under weakly acidic conditions.
- •
Strong acidic and weak basic conditions favor the red stability of NO-Heme.
- •
The color of NO-Heme changed from pink to yellow under strong basic conditions.
- •
Spectroscopic data shows how the conjugate structure of NO-Heme changes with pH.
