On a Lineweaver-Burk plot the y-intercept, or value at which the line intersects the y axis, is the reciprocal of Vmax. (If you need an algebra refresher, the reciprocal of any number "n" is 1/n.) Therefore, to get Vmax you should divide 1 by the y-intercept of the graph. This is expressed algebraically as Vmax = …... 2/04/2013 · The Lineweaver-Burk plot also known as the double reciprocal plot can be used to calculate Km and V max as well as determine the mechanism of action of enzyme inhibitors. In this plot we see that 1/v o is plotted versus 1/[S] and a straight line is obtained.

The intercepts don't really have physical meaning. The inverse of the Y intercept is the maximum rate and the inverse of the X is the Michaelis constant, but the Lineweaver-Burke equation itself is simply a linearization of the Michaelis-Menten equation so that it could be plotted and regressed by hand and/or with simple computers.

From the Michaelis Menten Kinetic equation, we have many different ways to find \(K_m\) and \(V_{max}\) such as the Lineweaver-Burk plot, Hanes-Woolf plot, and Eadie-Hofstee plot, etc. Lineweaver-Burk Plot

## How To Find Km From Lineweaver Burk Plot

### 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.

- Why the enzyme kinetics(Km) I got was negative? And the initial reaction rate came from good linear plot,but I calculate my Km and V max based on Lineweaver-burke plot they are negative values
- • Lineweaver-Burk plot shows that in the presence of increasing concentrations of inhibitor, I, o K M INCREASES o V max STAYS THE SAME o Effects of competition can be overcome by increasing [S] o K M gets larger, more substrate needed to reach a given rate, can still, however, ultimately achieve V max o Regardless of the concentration of a competitive inhibitor, a sufficiently high substrate
- From the Michaelis Menten Kinetic equation, we have many different ways to find \(K_m\) and \(V_{max}\) such as the Lineweaver-Burk plot, Hanes-Woolf plot, and Eadie-Hofstee plot, etc. Lineweaver-Burk Plot
- The intercepts don't really have physical meaning. The inverse of the Y intercept is the maximum rate and the inverse of the X is the Michaelis constant, but the Lineweaver-Burke equation itself is simply a linearization of the Michaelis-Menten equation so that it could be plotted and regressed by hand and/or with simple computers.
