Structures of alanine at pH = 2 and pH = 10 are respectively

Q: Structures of alanine at $pH = 2$ and $pH = 10$ are respectively

a Alanine zwitter ion is $\begin{array}{*{20}{c}} {C{H_3}\,\,} \\ {|\,\,\,\,\,\,\,\,} \\ {{H_3}\mathop N\limits^ \oplus - CH - CO{O^\Theta }} \end{array}$ $\begin{array}{*{20}{c}} {{H_3}\mathop N\limits^ \oplus - CH - COOH} \\ {|\,\,\,\,\,\,\,\,\,\,} \\ {C{H_3}\,\,} \end{array}$ $\underset{{O{H^\Theta }}}{\overset{{{H^ \oplus }}}{\longleftrightarrow}}$ $\begin{array}{*{20}{c}} {{H_3}\mathop {\mathop N\limits^ \oplus - CH - CO{O^\Theta }}\limits^{} } \\ {|{\mkern 1mu} {\mkern 1mu} {\mkern 1mu} {\mkern 1mu} {\mkern 1mu} {\mkern 1mu} {\mkern 1mu} } \\ {C{H_3}} \end{array}$ $\underset{{^\Theta OH}}{\overset{{{H^ \oplus }}}{\longleftrightarrow}}$ $\begin{array}{*{20}{c}} {{H_2}N - CH - CO{O^\Theta }} \\ {|\,\,\,\,\,\,\,\,} \\ {\,C{H_3}\,\,} \end{array}$
