Is N2O3 the main nitrosating intermediate in aerated nitric oxide (NO) solutions in vivo? If so, where, when, and which one?

Abstract

The widespread opinion that N 2 O 3 as a product of NO oxidation is the only nitros(yl)ating agent under aerobic conditions is based on experiments in homogeneous buffered water solutions. In vivo NO is oxidized in heterogeneous media and this opinion is not correct. The equilibrium in the system being dependent on temperature and Δ G(sol) for NO, NO 2, isomers of both N 2 O 3, and N 2 O 4. For polar solvents including water, Δ G(sol) for N 2 O 3 is high enough, and a stationary concentration of N 2 O 3 in the mixture with other oxides is sufficient to guarantee the hydrolysis of N 2 O 3 to nitrite. In heterogeneous media, the mixture contains solvates NO 2(sol), N 2 O 3(sol), and N 2 O 4(sol) at stationary nonequilibrium concentrations. As far as Δ G(sol) is decreased in heterogeneous mixtures with low polar solvents and/or at increased temperatures, the equilibrium in such a system shifts to NO 2. Although NO 2 is a reactive free radical, it almost does not react with water. In contrast, the reaction with most functional protein groups efficiently proceeds by a radical type with the formation of nitrite and new radicals (X) further stabilized in various forms. Therefore, the ratio of the nitrosylated and nitrated products yields depends on actual concentrations of all NOx. © 2002 Wiley Periodicals, Inc. J Biochem Mol Toxicol 16:109–120, 2002.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
