Lineweaver-Burk, Hanes, Eadie-Hofstee and Dixon plots can only be used when a true initial rate is measured. Despite the fact that this point has often been stressed, it is far too often ignored in favour of restricting the assay time to one where low amounts of substrate are used. When one or several irreversible and slow steps occur ...

Both Eadie-Hofstee and LineweaverBurk plots remain useful as a means to present data graphically. One drawback from the EadieHofstee approach is that neither ordinate nor abscissa represent independent variables: both are dependent on reaction rate. central steel works peterboroughWebThis is called the Eadie–Hofstee plot. As with the Lineweaver –Burk plot, the Eadie–Hofstee linearisation distorts errors in the data so that the method has reduced accuracy. 12.4.4. Langmuir PlotMultiplying Eq.
