    Which of the following compounds is an amino acid [Manipal MEE 1995]

    A)                 \[C{{H}_{3}}-C{{H}_{2}}-\overset{O}{\mathop{\overset{||}{\mathop{C}}\,}}\,-O-N{{H}_{4}}\]

    B)                 \[C{{H}_{3}}-\underset{N{{H}_{2}}\,}{\mathop{\underset{|\,\,\,\,\,\,\,\,\,\,\,}{\mathop{CH-}}\,}}\,\overset{O}{\mathop{\overset{||}{\mathop{C}}\,}}\,-OH\]

    C)                 \[C{{H}_{3}}-C{{H}_{2}}-\overset{O}{\mathop{\overset{||}{\mathop{C}}\,}}\,-N{{H}_{2}}\]

    D)                 \[C{{H}_{3}}-\underset{N{{H}_{2}}\,\,}{\mathop{\underset{|\,\,\,\,\,\,\,\,\,}{\mathop{CH-}}\,}}\,\overset{O}{\mathop{\overset{||}{\mathop{C}}\,}}\,-Cl\]

    Correct Answer: B

    Solution :

               \[C{{H}_{3}}-\underset{N{{H}_{2}}}{\mathop{\underset{|}{\mathop{C}}\,H}}\,-COOH\] The compounds in which both amino \[(-N{{H}_{2}})\]as well as acidic (?COOH) group is present is called amino acid.
