The structure of amino acid exists in the following two forms:
\[\begin{array}{cc}
\phantom{.........}\ce{O}\phantom{........................................}\ce{O}\phantom{.}\\
\phantom{.......}||\phantom{........................................}||\\
\ce{R - CH - C - OH <-->[aqueous] R - CH - C - O-}\\
|\phantom{..........................................}|\phantom{............}\\
\ce{NH2}\phantom{..................................}\ce{^+NH3}\phantom{........}\\
\end{array}\]
The above structure is an example of ______. If the side chain R is replaced by hydrogen, the amino acid is known as ______.
