Lineweaver Burk plot

The Lineweaver—Burk plot is a double-reciprocal plot, obtained by taking reciprocals of both sides of Equation (6.4) and rearranging: (6.5) 1 v = K m + [ S ] [ S ] V max (6.6) 1 v = K m V max 1 [ S ] + 1 V max 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 The Lineweaver-Burk plot (or double reciprocal plot) is a graphical representation of the Lineweaver-Burk equation of enzyme kinetics, described by Hans Lineweaver and Dean Burk in 1934. This plot is a derivation of the Michaelis-Menten equation and is represented as

A typical curve of enzyme kinetics is a plot of a plot of velocity of reaction vs substrate concentration. As the substrate concentration increases the veloc.. Yet the Lineweaver-Burk plot continues to be a useful visual tool, particularly because of its characteristic shifts in the presence of various types of inhibitors. So we'll create a Lineweaver-Burk plot with data points derived from double-reciprocal transformation, but we'll superimpose a line based upon nonlinear regression analysis, so that it reflects the best possible estimates of Kd and Bmax A good way of finding the Michaelis constant and the (half) maximum velocity of a certain enzyme reaction is to work with a linearized version of your data..
