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.

Design of a Pd–Au Nitrite Reduction Catalyst by Identifying and Optimizing Active Ensembles
ACS Catalysis, 2019Nitrate (NO3–) is a ubiquitous contaminant in groundwater that causes serious public health issues around the world. Though various strategies are able to reduce NO3– to nitrite (NO2–), a rational catalyst design strategy for NO2– removal has not been ...

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.

JAMA: The Journal of the American Medical Association, 1979
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

Toxic effects of nitrite on freshwater organisms: a review
, 2018High nitrite concentrations may occur mainly in recirculating aquaculture systems, but can also be found under certain conditions in natural waters. Among studied freshwater organisms, molluscs and worms followed by fish are the most resistant to nitrite.

Cobalt Metallopeptide Electrocatalyst for the Selective Reduction of Nitrite to Ammonium.
Journal of the American Chemical Society, 2018A cobalt-tripeptide complex (CoGGH) is developed as an electrocatalyst for the selective six-electron, eight-proton reduction of nitrite to ammonium in aqueous buffer near neutral pH. The onset potential for nitrite reduction occurs at -0.65 V vs Ag/AgCl

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.

Quantum Yield of Nitrite from the Photolysis of Aqueous Nitrate above 300 nm.
Environmental Science and Technology, 2017Photolysis of nitrate (NO3-) produces reactive nitrogen and oxygen species via three different channels, forming: (1) nitrogen dioxide (NO2) and hydroxyl radical (•OH), (2) nitrite (NO2-) and oxygen atom (O(3P)), and (3) peroxynitrite (ONOO-).
