Vedclass · Answer

(C) The $pI$ (isoelectric point) values for the given amino acids are as follows: $Asp$ $(pI = 3.0)$,$Gly$ $(pI = 6.0)$,$Lys$ $(pI = 9.8)$,$Arg$ $(pI = 10.8)$. The $pKa$ values of the side chains or the overall acidity of amino acids correlate with their $pI$ values. Acidic amino acids like $Asp$ have lower $pI$ values,while basic amino acids like $Lys$ and $Arg$ have higher $pI$ values. Therefore,the increasing order of $pKa$ values is $Asp < Gly < Lys < Arg$.

The increasing order of $pKa$ of the following amino acids in aqueous solution is $Gly, Asp, Lys, Arg$.
