Scientific Basis of the Calculator

The Km Value Calculator is grounded in the Michaelis-Menten equation, a cornerstone of enzyme kinetics validated by peer-reviewed studies. The formula used is:

Km = [S] × (Vmax - v) / v

• Km: Michaelis constant (µM), substrate concentration at half Vmax.
• [S]: Substrate concentration (µM).
• Vmax: Maximum reaction rate (µmol/min).
• v: Observed reaction velocity (µmol/min).

Derived from the Michaelis-Menten model, this equation assumes steady-state kinetics and is widely used in biochemical research (e.g., Michaelis & Menten, 1913). The calculator ensures accurate Km estimates, reflecting enzyme affinity for its substrate, provided inputs are experimentally valid.
