In biochemistry, a Hanes–Woolf plot, Hanes plot, or plot of against , is a graphical representation of enzyme kinetics in which the ratio of the initial substrate … 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.
