The procedure for determining the initial enzyme velocity and its transformation into defined enzyme units as well as suggestions for documentation of the results are presented.KeywordsEnzyme units; Michaelis–Menten equation; pH dependence; get redirected here Common to all enzyme-catalysed reactions is the fact that a substrate becomes converted into a product and thus the aim of any assay is to observe the time-dependent formation of the Click the icon above to update your browser permissions and try again Example: Reload the page to try again!
