Related people

An equation for enzyme-catalysed biological reactions relating the rate of formation of product to the concentration of enzyme and of substrate (reactant).

Description

An equation for enzyme-catalysed biological reactions relating the rate of formation of product to the concentration of enzyme and of substrate (reactant). This equation gives an expression for the rate of an enzyme reaction and became fundamental to the interpretation of how an enzyme reacts on its substrate. Before the work of Michaelis and Menten, Victor Henri in 1903 found that enzyme reactions were initiated by a bond between the enzyme and the substrate. From 1910 Michaelis and Menten took this work further, investigating the kinetics of an enzyme, saccharase, that catalyzes the hydrolysis of sucrose into glucose and fructose.

What is an eponym?

An eponym is a word derived from the name of a person, whether real or fictional. A medical eponym is thus any word related to medicine, whose name is derived from a person.
