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 inhibition can be compared to the uninhibited reaction. Competitive Inhibition Vmax is unaffected by competitive inhibitors. … 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 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 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 • Michaelis–Menten kinetics • Eadie–Hofstee diagram • Hanes–Woolf plot Se mer • NIH guide, enzyme assay development and analysis Se mer Nettet8.23K subscribers. A recap of the Michaelis-menten plots of enzyme inhibition are initially recalled, followed by their conversion to their corresponding Lineweaver-Burk plots.
