Michaelis–Menten Kinetics
In biochemistry, Michaelis–Menten kinetics, named after Leonor Michaelis and Maud Menten, is the simplest case of enzyme kinetics, applied to enzyme-catalysed reactions involving the transformation of one substrate into one product. It takes the form of a differential equation describing the reaction rate v (rate of formation of product (biology), product P, with concentration p) as a function of a, the concentration of the Enzyme substrate (biology), substrate A (using the symbols recommended by the IUBMB). Its formula is given by the Michaelis–Menten equation: : v = \frac = \frac V, which is often written as V_\max, represents the limiting rate approached by the system at saturating substrate concentration for a given enzyme concentration. The Michaelis constant K_\mathrm has units of concentration, and for a given reaction is equal to the concentration of substrate at which the reaction rate is half of V. Biochemical reactions involving a single substrate are often ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Leonor Michaelis
Leonor Michaelis (16 January 1875 – 8 October 1949) was a German biochemist, physical chemist, and physician.
