Using Microsoft Excel to Plot and Analyze Kinetic Data

By creating a double-reciprocal plot (or Lineweaver-Burk plot) the values m max for K and V can be determined from a regression line through the values for 1/S vs. 1/v.

Lineweaver-Burke Problems

Lineweaver-Burk Problems 1) The initial rate for an enzyme catalyzed reaction has been determined at a number of substrate concentrations. Data are as follows [S] (umoles/L) V (umoles/L/min) 5 22 10 39 20 65 50 102 100 120 200 135 a) Use a Lineweaver-Burk plot (1/[S] vs 1/V) to determine Vmax ...

Using Microsoft Excel to Plot and Analyze Kinetic Data

Three plots were ® produced from each assay, one representing the Michaelis-Menton equation and the other two representing linearized forms of that equation, specifically a double-reciprocal plot called a Lineweaver-Burk plot and an m max Eadie-Hofstee plot.

The Lineweaver Burk "double reciprocal" plot allows for analysis of enzymatic data when V max has not been clearly reached. The derivation is as follows:
