reaction mechanism Enzyme Given Km find substrate concentration at a certain
Lineweaver-Burk analysis is one method of linearizing substrate-velocity data so as to determine the kinetic constants Km and Vmax. One creates a secondary, reciprocal plot: 1/velocity vs. 1/ [substrate].

Lineweaver-Burk Plots. The Michaelis-Menten equation is useful in other ways, too. If we take its inverse, we get a new relationship. That's useful because it's really an expression for a straight line. If we plot 1/v against 1/[S], we get a straight line. The slope is K m /V max and the y intercept is 1/V max. Lineweaver-Burk plot gives a.

The Lineweaver-Burk equation of enzyme kinetics is represented graphically by the Lineweaver-Burk Plot (also known as the double reciprocal plot), which was first introduced by Dean Burk and Hans Lineweaver in 1934. It is difficult to predict Vmax and, consequently, Km from a hyperbolic plot since Vmax is reached at an infinite substrate.

Figure 4.9.1: Line-Weaver Burk Plot. For a Lineweaver-Burk, the manipulation is using the reciprocal of the values of both the velocity and the substrate concentration. The inverted values are then plotted on a graph as 1 / V vs. 1 / [ S ]. Because of these inversions, Lineweaver-Burk plots are commonly referred to as 'double-reciprocal' plots.
