The velocity v with which a protein moves through water under the influence of an electric field varied with values of pH in the range 3.0<pH<7.0 according to the expression v/( ųms-1)=a+b(pH)+c(pH)^2+ d(pH)^3 with a=0.50, b=-0.10, c=-3.0*10^-3, and d=5.0*10^-4. Identify the isoelectric point of the protein.

Expert Solution

Step 1

At the isoelectric point, the net charge on a protein is zero, or we can say that it does not move under the influence of electric point at a pH equal to its isoelectric point.
