The application of enzymes for leather processing enhances the quality of leather and gives stronger and softer leather with less The enzyme-assisted plant protein extraction process involves the selection of enzyme preparation(s), optimisation of hydrolysis conditions and performance of the hydrolysis reaction under selected parameters, termination of the reaction by inactivation of the enzyme (or by its separation) and finally recovery of the proteinaceous fractions (Fig. In a study of the enzyme, you find the initial velocities (mM/h) are dependent on the initial substrate concentration. 6˚F. (a) State three variables that the student would need to control in order to make the results of this investigation valid. Originating from its inactive precursor pepsinogen, pepsin becomes active in the acidic environment of gastric juice, emphasizing its importance in the initial stages of protein digestion. As the concentration of either is increased the rate of reaction increases (see graphs).
