Verified step by step guidance

Step 1: Understand the concept of peptide hydrolysis. Hydrolysis of a peptide involves breaking the peptide bonds between amino acids using water, resulting in the release of individual amino acids.

Step 2: Identify the amino acids present in the tripeptide Gly-Ala-Ser. The tripeptide is composed of glycine (Gly), alanine (Ala), and serine (Ser).

Step 3: Recall that during complete hydrolysis, all peptide bonds are cleaved, leaving the individual amino acids as products. For Gly-Ala-Ser, this means breaking the bond between Glycine and Alanine, and the bond between Alanine and Serine.

Step 4: Write the chemical reaction for hydrolysis: Gly-Ala-Ser + H₂O → Glycine + Alanine + Serine. This reaction shows the addition of water molecules to break the peptide bonds.

Step 5: Verify the products. After hydrolysis, the resulting amino acids are glycine, alanine, and serine. These are the correct products of the complete hydrolysis of the tripeptide Gly-Ala-Ser.
