Question

The structures of glycine and alanine are given below. Show the peptide bond linkage in glycylalanine.

\[\ce{\underset{Glycine}{H2N - CH2 - COOH}}\];

\[\begin{array}{cc}
\ce{CH3}\phantom{..}\\
|\phantom{.....}\\
\ce{\underset{Alanine}{H2N - CH - COOH}}\
\end{array}\]

Answer 1

\[\ce{\underset{Gylcine}{NH2CH2COOH}+\underset{alanine}{NH2CH}(CH3)COOH->\underset{glycylalanine}{NH2CH2[CONH]CH}(CH3)COOH + H2O}\]
