  • question_answer
    The \[p{{K}_{{{a}_{1}}}}\] and \[p{{K}_{{{a}_{2}}}}\]of an amino acid are 2.3 and 9.7 respectively. The isoelectric point of the amino acid is

    A)  12.0                                      

    B)  7.4

    C)  6.0                                        

    D)  3.7

    Correct Answer: C

    Solution :

                     Isoelectric point of amino acid \[=\frac{p{{K}_{{{a}_{1}}}}+p{{K}_{{{a}_{2}}}}}{2}\]                 \[=\frac{2.3+9.7}{2}\]                 \[=\frac{12}{2}=6.0\]
