The isoelectric point, pl, of the protein pepsin is 1, while that of clostripain is \( \mathbf{4 . 8} \). What is the net charge of pepsin at pH 5.1 ? What is the net charge of clostripain at pH 2.5 ? The isoelectric point of glutamine is \( \mathbf{5 . 6 5} \); tryptophan , \( \mathbf{5 . 8 9} \). During paper electrophoresis at pH 5.1, toward which electrode does glutamine migrate? During paper electrophoresis at pH 6.5 , toward which electrode does tryptophan migrate positive negative
