There are several ways to transform the Michaelis-Menten
equation so as to plot data and derive kinetic parameters, cach
with different advantages depending on the data set being
analyzed. One transformation of the Michaelis-Menten
equation is the Lineweaver-Burk, or double-reciprocal,
equation. Multiplying both sides of the Lineweaver-Burk
equation by Vmax and rearranging gives the
Eadie-Hofstee equation.

Consider the plot of Va versus
reaction. The control reactions (blue curve) did not contain
any inhibitor.
