The Lineweaver-Burk plot was widely used to determine important terms in enzyme kinetics, such as K m and V max before the wide availability of powerful computers and …
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. Nettetalso known as Lineweaver and Burk plot. Thisisnotatrivialquestion.Wehaveobservedthatin some practical instances, a Michaelis constant deter-mined with this procedure may di⁄er up to 150% from that evaluated with nonlinear regression. We can also show that the use of simple linear regression applied …

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 Lineweaver–Burk … Se mer $${\displaystyle [S]}$$: substrate concentration. The independent axis of a Lineweaver-Burk plot is the reciprocal of substrate concentration, $${\displaystyle {\frac {1}{[S]}}}$$. $${\displaystyle V}$$ or $${\displaystyle V_{0}}$$: … Se mer When used for determining the type of enzyme inhibition, the Lineweaver–Burk plot can distinguish competitive, pure non-competitive Se mer • Michaelis–Menten kinetics • Eadie–Hofstee diagram • Hanes–Woolf plot Se mer The plot provides a very useful graphical method for analysis of the Michaelis–Menten equation, as it is difficult to determine precisely the Vmax of an enzyme-catalysed reaction: $${\displaystyle V={\frac {V_{\max }[S]}{K_{m}+[S]}}}$$ Se mer While the Lineweaver-Burk is useful for determining important variables in enzyme kinetics, it is prone to error. 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
