Question
A synthetic amino acid has an ionizable side change (-OH) with a pKa of 6.54. Determine the isoelectric point for the amino acid. The other pKa values are 2.87 and 9.14. A. 6.54 B.7.84 C.6.00 D.4.71
Expert Solution
Step 1

Isoelectric point is the pH at which the amino acid does not migrate in an electric field and has net charge of zero. Form of amino acids present at pH equal to pI is known Zwitter Ion.
