\[\ce{\underset{Glycine}{H2N - CH2 - COOH}}\];
\[\begin{array}{cc}
\ce{CH3}\phantom{..}\\
|\phantom{.....}\\
\ce{\underset{Alanine}{H2N - CH - COOH}}\
\end{array}\]
The structures of two amino acids, glycine and alanine, are given below. Draw the peptide linkage between these two amino acids.

|\phantom{....}\\
\ce{H2N - C - COOH}\\
|\phantom{....}\\
\ce{\underset{(Glycine)}{H\phantom{....}}}\\
\end{array}\]
\[\begin{array}{cc}

Solution
\[\ce{\underset{Gylcine}{NH2 - CH2 - COOH}+\underset{Alanine}{NH2 - CH}(CH3) - COOH->\underset{Glycylalanine}{H2N - CH2 - CO - NH - CH}(CH3) - COOH + H2O}\]
