Progress-curve analysis in enzyme kinetics. Numerical solution of integrated rate equations

Area of Science:

• Biochemistry
• Chemical Kinetics

Background:

• Enzyme-catalyzed reactions generate progress curves described by complex equations.
• Direct calculation of reaction extent from these equations is often precluded.
• Existing methods like Newton-Raphson may be unreliable for these calculations.

Purpose of the Study:
