... of stimulatory ammonium about half of the total NADH-supported hydrogen peroxide production is catalyzed by Complex I. In the presence of ammonium about 90% of the total hydrogen peroxide production is catalyzed by matrix located, ammonium-dependent ...
... Title: . Ammonium-dependent hydrogen peroxide production by mitochondria. Authors: . ... I is not the major contributor to mitochondrial superoxide (hydrogen peroxide) generation and that there are specific ammonium ...
... brain homogenates with 70 microM hydrogen peroxide significantly influenced the profile of amyloid-beta binding proteins and 0.1 mM isatin decreased the number of identified amyloid-beta binding proteins both in control and hydrogen peroxide treated brain ...
... We suggest that the Ea activation barrier in the Pr* S1 excited state might correspond to the D-ring (C19) carbonyl - H290 hydrogen bond or possibly to the hindrance caused by the C13(1) /C17(1) methyl groups of the C and D rings. ...
... comparison of superoxide-mediated cytochrome c reduction with hydrogen peroxide-mediated Amplex Red oxidation suggests that complex I within its native environment (submitochondrial particles) produces both superoxide (~50%) and hydrogen peroxide (~50 ...
