Lineweaver plot
NettetLinear regression assumes that the scatter of points around the line follows a Gaussian distribution and that the standard deviation is the same at every value of X. These assumptions are rarely true after transforming data. Furthermore, some transformations alter the relationship between X and Y. NettetUse.

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 plot for inhibited enzymes can be compared to no inhibitor to determine … Se mer $${\displaystyle [S]}$$: substrate concentration. The independent axis of a Lineweaver-Burk plot is the reciprocal of substrate concentration, $${\displaystyle {\frac {1}{[S]}}}$$. $${\displaystyle V}$$ 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 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.

NettetThe 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: owenton ky weekly weatherNettetI katalytisk kjemi og biokjemi betegner Lineweaver–Burk-plottet en grafisk fremstilling av Lineweaver–Burk-ligningen av enzymkinetikk, beskrevet av Hans Lineweaver og … owenton ky manorNettetA single band of the purified inhibitor was obtained by Native-PAGE. SDS–PAGE revealed the purified inhibitor to be a monomer with molecular weight of 13,900 daltons.

An alternative is to plot the reciprocal of the Michaelis-Menten equation, which is (after all terms have been rearranged): \frac {1} {V}=\frac {K_M} {V_ {max} [S]}+\frac {1} {V_ {max}} V 1 = V … owen toothNettetUse. 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 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. rangers cup final 2023NettetTo determine the V max from a Lineweaver-Burk plot you would: A. Multiply the reciprocal of the x-axis intercept by -1. B. Multiply the reciprocal of the y-axis intercept by -1. C. Take the reciprocal of the x-axis intercept. D.
