Vmax

Definition

The maximum initial velocity or rate of a reaction.


Supplement

In enzyme kinetics, Vmax is the maximum velocity or rate at which the enzyme catalyzed a reaction. It happens when all enzyme active sites are saturated with substrate.

Since the maximum velocity is described to be directly proportional to enzyme concentration, it can therefore be used to estimate enzyme concentration.

Help with a question

... I. However after drawing the Michaelis Menten plot you observe that even at the maximum concentration of inhibitor that you have been given, the Vmax for the inhibited reaction is lower than the un-inhibited reaction Describe how you would have derived the data for the Michaelis Menten plot, ...

Enzyme Kinetics - Turnover

... and the reaction volume to give me velocity in "moles of product formed/min". I used this to then plot a lineweaver burke plot to get Vmax and Km values. One of the questions asks me to calculate the Kcat value. This is where i'm stuck. I have the following data at hand: Vmax = 2.442 ...
