Explanation:
Detailed explanation-1: -Gly-Ala is a dipeptide formed from glycine and L-alanine residues.
Detailed explanation-2: -If the amino group of glycine and carboxylic acid group of alanine undergo elimination of water molecule, the formed compound is glycylalanine (dipeptide).
Detailed explanation-3: -An amino acid contains both an amino group, -NH2, and a carboxylic acid group, -COOH, in the same molecule.
Detailed explanation-4: -The amino acids differ from each other in the particular chemical structure of the R group.
