Estimation of the overall kinetic parameters of enzyme inactivation using an isoconversional method [PDF]

open access: yesBiophysical Chemistry, 2008
An isoconversional method is proposed in order to calculate the kinetic parameters of enzyme inactivation. The method provides an efficient and low-cost procedure to describe both operational and thermal inactivation. Unlike the ordinary kinetic assays performed at constant enzyme concentration and at various substrate concentrations, the ...

The catalytic thermo-oxidative decomposition of glimepiride using the isoconversional method

open access: yesJournal of Thermal Analysis and Calorimetry, 2022
AbstractApplying the isoconversional method to data obtained from thermogravimetric analysis (TGA) can provide vital kinetic information. In this work, the thermal decomposition and oxidation of the antidiabetic drug glimepiride is analyzed in the presence of N2and O2. The study was done with and without metal oxide catalysts to explore their potential
