In biochemistry, the Lineweaver–Burk plot (or double reciprocal plot) is a graphical representation of the Michaelis–Menten equation of enzyme kinetics, described by Hans Lineweaver and Dean Burk in 1934. The double reciprocal plot distorts the error structure of the data, and is therefore not the most accurate tool for the determination of enzyme kinetic parameters. While the Lineweaver–Burk pl… WebLineweaver-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]. When catalytic activity follows Michaelis-Menten kinetics over the range of substrate concentrations tested, the Lineweaver-Burk plot is a ...
