Answer
As we know that peptide bond is a type of bond present between amino acids, an is formed when one carboxyl group of one amino acid join with the amino group of another amino acids through the process of condensation and water is released in this process.
Types of peptides
Those peptide which consist of only one peptide bond and two amino acid is known as monopeptide. Dipeptide is composed of three amino acids and two peptide bond, while tripeptide is composed of four amino acids and three peptide bonds.
Hydrolysis
it is a type of reaction in which polymers are broken down into monomers with the help of water.
If a protein molecule which is composed of only four amino acids, it means that they require three peptide bond for holding them in protein. so three peptide bonds are present in its structure. To break these bond they need just three water molecules.
