Se utilizó un modelo cinético para estudiar la velocidad de reacción en la hidrólisis de proteínas de plasma de bovino con alcalasa 2,4 L en un reactor batch. Se estudió la influencia de variables como la concentración inicial de sustrato y enzima sobre el grado de hidrólisis y se determinaron los parámetros cinéticos de la ecuación de velocidad, analizando su relación con las variables de trabajo. Se ajustó un modelo cinético de orden cero y desactivación enzimática por sustrato, de segundo orden, así como la relación directa entre la fracción enzima-sustrato y la tasa de formación de productos de hidrólisis.

Abstract: A kinetic model was used to study the reaction rate of hydrolysis of bovine plasma proteins and alcalase 2.4 L, in a batch reactor. The influence of variables, such as the concentration of initial enzyme substrate and the degree of hydrolysis was studied, and kinetic parameters of the rate equation were determined by analyzing its relationship with the work variables. A zero-order kinetic model and enzyme deactivation by substrate was found, as well as the direct relationship between the fraction of enzyme-substrate and the rate of formation of hydrolysis products.
