The first chapter is a summary of recent
publications about the effect of HNO in the
cardiovascular system, detection of HNO in vitro,
and physiological reactivity of HNO. The second
chapter provides synthetic details of a newly
developed method of a synthesis of HNO-Mb of high
purity ( 95%). The transient absorbance studies of
HNO-Mb revealed completely different results than
that of other myoglobin adducts such as MbO2 and NO-
Mb. Formation of the Mb-Fe(III)/HNO- geminate pair
was confirmed by analyses of transient absorbance
spectra at 395 nm. In the third chapter rate
constants of the reaction of HNO with Mb-Fe(II), Mb-
Fe(III), HNO-Mb, and HNO-Mb with oxygen and
nitric oxide were determined using the
computational software React for Windows. In
addition to the computational method, a direct
method of comparison of the rates of the reaction
of HNO with proteins was developed. In the last
chapter synthesis of HNO adduct of hemoglobin is
reported. UV-vis, EPR, and 1H NMR spectroscopic
techniques were used to identify and differentiate
the hydride peaks of HNO subunits of hemoglobin.
