Lineweaver burk method

NettetIn the method of Lineweaver and Burk (1934), a plot is generated from 1/v versus 1/ [S] data. The linear equation used to determine the parameters is given by: The slope of the line equals K m /V max, the x intercept represents 1/K m in second quadrant and the y intercept is 1/V max. In Eadie-Hofstee plot, v/ [S] values are plotted against v. NettetEadie–Hofstee diagram. In biochemistry, an Eadie–Hofstee diagram (more usually called an Eadie–Hofstee plot) is a graphical representation of the Michaelis–Menten equation in enzyme kinetics. It has been known by various different names, including Eadie plot, Hofstee plot and Augustinsson plot. Attribution to Woolf is often omitted ...

NettetThe 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 non-linear regression software, as the y-intercept of such a graph is equivalent to the inverse of V max; the x-intercept of the graph represents -1/K m. 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.
