Accepted mechanism is based on rapid reaction of native MPO with HOto produce Compound I (MPO-I) which oxidizes Clthrough a 2e鈥 transition generating MPO and HOCl. MPO-I also reacts with HOto generate Compound II (MPO-II) which is inactive in 2e oxidation of Cl. Nitrite ( NO) ...
In the presence of physiological concentrations of chloride (Cl−), MPO utilizes H2O2 to generate the potent oxidant hypochlorous acid (HOCl) [3], [4], [5]. HOCl reacts with many biological targets [5], and particularly rapidly with sulfur- and selenium-containing species [6], [7], [...
Drinking water production faces many different challenges with one of them being naturally produced cyanobacterial toxins. Since pollutants become more abundant and persistent today, conventional water treatment is often no longer sufficient to provide adequate removal. Among other emerging technologies, advan...
32 found that SO2 was rapidly oxidized on the NaOCl aerosol which produced HOCl in solution. To examine whether the simultaneous presence of Mn2+, O2, and Cl– in aerosol liquid water would facilitate HOCl formation, chamber experiments were also conducted under the NaNO3 seed condition. As ...
Oxygen evolution reaction (OER) is an important electrochemical half-reaction in water electrolysis, but its slow kinetics has severely restricted the overall catalytic/energy efficiency for hydrogen production1,2,3,4. Recently, the electro-oxidation of biomass-derived molecules (such as aldehydes, alc...
(9)). Furthermore, adsorbed chloride ions on the semiconductor surface could also be directly oxidized by photo-generated h+ under UV irradiation leading to the formation of Cl•/HOCl• species (Eq. (10)). In the absence of competitive reactions with pathogens, the formation of active ...
Which of the following is best described as an oxidation-reduction reaction? A) SO2(g) + H2O(l) -> H2SO3(aq) B) 2Cl(g) -> Cl2(g) C) 3O2(g) -> 2O3(g) D) 2NO2(g) -> N2O4(g) E) SO2(g) + O2(g) -> SO3(g) How do you know?
log [H+] was linear with a negative slope (-0.52) (Table 1 and Figure 3) indicating an inverse fractional-order dependence in [H+]. The addition of Cl- or Br– ions as NaCl or NaBr had no effect on the rate, suggesting no role of halid...
of reactive oxygen species (ROS), such as HOCl, HOBr and ·NO145,146. In contrast to products of enzymatic lipid oxidation, the products of non-enzymatic processes are considered to be more toxic and damaging to the host147. Continuous degradation of lipid-hydroxyperoxides by cyclization and ...
Advanced oxidation protein products (AOPPs), a novel protein marker of oxidative damage, have been confirmed to accumulate in patients with inflammatory bowel disease (IBD), as well as those with diabetes and chronic kidney disease. However, the role of AOPPs in the intestinal epithelium remains...
