Publisher's Synopsis
Excerpt from The Influence of Alpha Methyl Glucoside on the Invertase, Hydrolysis of Sucrose
Michaelis and Mentong, (biochem. Zeit. 49; 333; 1913) by plotting the relative initial velocity of hydrolysis of sucrose by invertase against the logarithm of the initial molar sucrose con centration, obtained data which are represented by the points in Figure 1. (the relative rates are compared by considering the maximum rate as 100 and the other rates as percents of this maximum.) These points they conclude, indicate a dissociation rest curve (discussed on page 20 represented by the heavy graph in the same figure. That is, they claim their results Show that invertase and sucrose combine to form a compound accord ing to the Mass Law and that the rate of hydrolysis is propor tional to the amount of invertase-sucrose compound present. This view of the mechanism involved in the reaction has aroused considerable interest among investigators in the field of Enzyme Chemistry. Euler, (chemie der Enzyme, Munich, 1920) con siders it to be a contribution equal in importance to Sorensen's study of hydrogen ion concentrations as related to enzymes.
