Lineweaver burk plot definition
NettetCreate a Lineweaver-Burk plot Before nonlinear regression was available, investigators had to transform curved data into straight lines, so they could analyze with linear regression. One way to do this is with a Lineweaver-Burk plot, which plots the reciprocal of substrate concentration vs. the reciprocal of enzyme velocity. NettetUse. 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 …
