Nitrite in paraffin-stimulated saliva correlates with blood nitrite
Nitric Oxide, 2021Nitrite anion (NO2-) is a circulating nitric oxide (NO) metabolite considered an endothelial function marker. Nitrite can be produced from nitrate (NO3-) secreted from plasma into saliva. The nitrate reductase of oral bacteria converts salivary nitrate to nitrite, which is swallowed and absorbed into circulation.

Nitrite coordination in myoglobin
Journal of Inorganic Biochemistry, 2017The coordination of nitrite in myoglobin (Mb) has been characterized by resonance Raman spectroscopy and the frequencies of the nitrite bound to the heme Fe as well to the 2-vinyl have been computed by density functional theory (DFT) calculations. The DFT Natural Bond Orbital (NBO) analysis and the extensive isotope-labeling in the resonance Raman ...

Photometric determination of nitrite
Talanta, 1981A new sensitive colour reaction for nitrite determination is presented. The method is based on the reaction of nitrite with p-aminobenzoic acid to form a diazonium ion, which is coupled with 8-hydroxyquinoline, in alkaline medium, to form a reddish-orange water-soluble azo dye.

AMYL nitrite was introduced into medical practice as a coronary vasodilator more than a century ago; for much of that time, it was a mainstay, along with nitroglycerin, for angina pectoris. At present it is not used much, having been displaced by the organic nitrates. However, amyl nitrite along with its six-carbon analog, isobutyl nitrite, has come on

Denitrification and nitrite reduction: Pseudomonas aeruginosa nitrite-reductase
Biochimie, 1984Present knowledge of the different enzymatic steps of the denitrification chains in various bacteria, particularly Paracoccus denitrificans and Pseudomonas aeruginosa has been briefly reviewed. The question whether nitric oxide (NO), nitrous oxide (N2O) and other nitrogen derivatives are obligatory intermediates has been discussed.

The official U.S.P. assay for sodium nitrite which employs standard permanganate and standard oxalate solutions is compared with a new method using standard ceric sulfate solution. The proposed method is shown to be more accurate than the official method by comparison of the results with the absolute purity of the sodium nitrite determined by phase ...
