Michaelis-menten equation

Michaelis-menten equation
(Science: chemistry) equation derived from a simple kinetic model for a singlesubstrate non-cooperative enzyme-catalyzed reaction that successfully accounts for the hyperbolic adsorption isotherm) relationship between substrate concentration and reaction rate.
v = vmax x S/(s – Km), where v is the initial velocity of the reaction, Km is the michaelis constant, vmax is the maximum rate approached by very high substrate concentrations and s is the initial substrate concentration.
similar equations can be derived for conditions in which the product is present and for multisubstrate enzymes.
Synonym: victor-Michaelis-Menten equation.
