Peroxynitric acid inhibits amyloid β aggregation
Biochemical and Biophysical Research Communications, 2023Peroxynitric acid (PNA), a reactive oxygen nitrogen species, has attracted attention in life science because of its unique properties such as high bacteriacidal activity. Since the bactericidal activity of PNA could be related to its reaction with amino acid residues, we speculate that PNA can be used for protein modifications.

A weak CL emission was initiated by peroxynitrous acid (PA) produced by the interaction of nitrite with hydrogen peroxide in sulphuric acid solution. In the presence of nitrogen doped carbon dots (NCDs), the CL intensity was enhanced significantly.

Rapid scavenging of peroxynitrous acid by monohydroascorbate
Free Radical Biology and Medicine, 2003The reaction of peroxynitrous acid with monohydroascorbate, over the concentration range of 250 microM to 50 mM of monohydroascorbate at pH 5.8 and at 25 degrees C, was reinvestigated and the rate constant of the reaction found to be much higher than reported earlier (Bartlett, D.; Church, D. F.; Bounds, P. L.; Koppenol, W. H. The kinetics of oxidation

Photon-Initiated Homolysis of Peroxynitrous Acid
Inorganic Chemistry, 2009Laser flash photolysis of ONOOH at 355 nm and a pH of 4.0-5.5 causes homolysis of ONOOH nearly exclusively at the N-O bond rather than at the O-O bond (HO(2)(*)/HO(*) > 25:1). All of the NO(*) and HO(2)(*) radicals formed by photolysis subsequently recombine with a rate constant of (1.2 +/- 0.2) x 10(10) M(-1) s(-1) via second-order kinetics, as ...

Internal rotation in peroxynitrous acid (ONOOH)
The Journal of Chemical Physics, 2005Using higher levels of wave-function-based electronic structure theory than previously applied, as well as density functional theory (B-LYP and B3-LYP functionals), all theoretical models conclude that three ONOOH conformers are stationary point minima, in disagreement with some of the previous studies that we survey.

Oxidation of Nitrite by Peroxynitrous Acid
The Journal of Physical Chemistry A, 2003The kinetics of the oxidation of nitrite to nitrate by peroxynitrous acid at pH 5.2 is best described by the rate law kobs = kiso + k‘[NO2-] + k‘ ‘[NO2-]2, in which the peroxynitrous acid isomerization rate constant kiso = (1.10 ± 0.05) s-1, k‘ = (3.2 ± 0.1) M-1 s-1, and k‘ ‘ = (4.2 ± 0.3) M-2s-1, at 25 °C.
