Nettet30. mai 2024 · The Lineweaver–Burk plot (or double reciprocal plot) is a graphical representation of the Lineweaver–Burk equation of enzyme kinetics, described … The Lineweaver-Burk plot derives from a transformation of the Michaelis-Menten equation , in which the rate is a function of the substrate concentration and two parameters , the limiting rate, and , the Michaelis constant. Taking reciprocals of both sides of this equation it becomes as follows: Se mer In biochemistry, 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.

The y-axis of the plot takes the reciprocal of the rate of reaction, meaning small errors in measurement are more noticeable. Additionally, the … Se mer • NIH guide, enzyme assay development and analysis Se mer

NettetAs a double reciprocal plot, the Lineweaver-Burk plot presents two problems when used with real life experimental data. First, all data found at large substrate concentrations will be clustered near the origin. Second, small experimental errors are magnified on Lineweaver-Burk plots, particularly for the points that lie far away from the origin.
