Expert Solution
Step 1

Alpha carbon of amino acids consist of carboxyl, amine group and side chain group. Based on the side chain group, amino acids can be charged polar, uncharged polar and non-polar. It makes amino acids hydrophobic and hydrophilic. The carboxylic group of one amino acid condenses with amine group of another amino acid with release of one water molecule and thus by this condensation reaction it forms peptide bond. Similarly, during the hydrolysis of peptide bond one water molecule is utilized.
