- For protein X, you do not know the extinction coefficient of the substrate to calculate the true concentration. Therefore you are planning to calculate the initial rate of reaction as a change in absorbance per unit of time. After you did the experiment, you found that the the straightest portion of your graph is between 0 minute and 1 minute, and the absorbance changes from 0.865 to 0.132 within one minute.
