Hydrogen peroxide oxidation guaiacol. Medical search. Frequent questions

The enzyme of turnip peroxidase is added in the equation to catalyze the oxidation. (ipl.org)
The guaiacol assay, for example, which is one of the most commonly used assays for peroxidase activity, is sensitive to both eosinophil peroxidase (EPO) and the peroxidase of neutrophils, i.e., myeloperoxidase (MPO), thus preventing distinction of the two peroxidases in mixed neutrophil-eosinophil populations. (nih.gov)
The method is based on the peroxidase-mediated oxidation of homovanillic acid (HVA) under appropriate assay conditions in which EPO is still very active in catalyzing the reaction whilst MPO-mediated HVA oxidation is almost undetectable. (nih.gov)
L-dopa) and that catalase maintained at alkaline pH for various lengths of time demonstrates an increase in peroxidase activity using guaiacol as substrate. (nih.gov)
To evaluate an oxidative response in different organs, hydrogen peroxide, superoxide anion, catalase, ascorbate peroxidase, guaiacol peroxidase, and superoxide dismutase activity were evaluated in fruit and leaves. (frontiersin.org)

Catalase is an enzyme which can function either in the catabolism of hydrogen peroxide or in the peroxidatic oxidation of small substrates such as ethanol, methanol, or elemental mercury (Hg0). (nih.gov)

The substrate in our experiment was 0.1% hydrogen peroxide. (ipl.org)
When we mixed pH 3 enzyme tube with substrate tube, we used 0.3 mL of hydrogen peroxide, but if we were to increase the amount, then the experiment would have been faster. (ipl.org)
In this experiment, the reducing agent guaiacol is added with the substrate, hydrogen peroxide, to create water and oxygen. (ipl.org)

The aim of the study is investigations of T213R/T214I CYP119 whether it is a stable and efficient biocatalyst for selective oxidation of hydrocarbons, which does not require expensive cofactors and electron transfer proteins or not. (iyte.edu.tr)

Characterization of T213R/T214I CYP119 shows higher peroxidation activity of enzyme for Amplex® Red, guaiacol and ABTS and epoxidation of enzyme for styrene substrates compared to CYP119. (iyte.edu.tr)

C6H4(OH)2 + H2O}}} It can be produced by reaction of salicylaldehyde with base and hydrogen peroxide (Dakin oxidation), as well as the hydrolysis of 2-substituted phenols, especially 2-chlorophenol, with hot aqueous solutions containing alkali metal hydroxides. (wikipedia.org)

In our laboratories, directed evolution was used to create improved mutants of CYP119 with higher oxidation activity when using H2O2. (iyte.edu.tr)
