NettetLineweaver-Burk plot analysis is the most widely used method to determine enzyme kinetic parameters. In the spectrophotometric determination of enzyme activity using … 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, $${\displaystyle {\frac {1}{[S]}}}$$ Se mer When used for determining the type of enzyme inhibition, the Lineweaver–Burk plot can distinguish competitive, pure non-competitive and uncompetitive inhibitors. The various modes of … 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.
