Abstract

Quantitative kinetic data are given on the oxidation reaction of dioxyfumaric acid (DFA) with atmospheric oxygen in the presence of horseradish peroxidase (HRP) depending on pH. Activation constants of oxidation with hydrogen peroxide and Mn ions are determined at pH 3.0. Autocatalytic character of FRA oxidation is shown to be due to the formation of H2O2 and other hydro peroxide-type compounds in the reaction, HRP convertions in the DFA--O2 system are studied using spectrophotometry. A mechanism of the initiation of free radicals in HRP--DFA--O2 system is proposed.

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.
