Write the structure of all possible dipeptides which can be obtained form glycine and alanine

Explanation

(i) `underset(("Glycine"))(H_(2)N-CH_(2)-)COOH+H_(2)N-underset(("Alanine"))underset(CH_(3))underset(|)(CH)-COOHunderset(-H_(2)O)toH_(2)N-CH_(2)-underset(("Glycyl alanine"))(CONH-underset(CH_(3))underset(|)(CH)-COOH`
(ii) `H_(2)N-underset(("Alanine"))underset(CH_(3))underset(|)(CH)-COOH+H_(2)Nunderset(("Glycine"))(-CH_(2)-)COOH underset(-H_(2)O)to underset(("Alanyl glycine"))underset(CH_(3))underset(|)(H_(2)N-CH-CO)NH-CH_(2)-COOH`
Therefore two dipeptides structures are possible from glycine and alanine. They are (i) glycyl alanine and (ii) Alanyl glycine
