Sketch a titration curve of the amino acid glutamate with pH on the y-axis and volume of titrant on the x-axis. Label each axis appropriately. Draw the chemical structures of the 4 possible forms of glutamate in aqueous solution. Indicate on the graph the following: where each of the species predominates, the pKa values and the isoelectric point.

Sketch a titration curve of the amino acid glutamate with pH on the y-axis and volume of titrant on the x-axis. Label each axis appropriately. Draw the chemical structures of the 4 possible forms of glutamate in aqueous solution. Indicate on the graph the following: where each of the species predominates, the pKa values and the isoelectric point.
Expert Solution
Step 1
Let the titrant added be NaOH (in mL) which is plotted on the x-axis and the pH on the y-axis. Glutamate in its most protonated form is represented as below:
