22 water molecules are required to completely hydrolyze a polypeptide made up of 23 amino acids.
How does hydrolysis of proteins take place?
- Protein is made up of a chain of amino acids.
- Amino acids are linked together by a peptide bond.
- When the carboxyl group of one molecule combines with the amino group of the other molecule, a molecule of water is released, and a peptide bond is created between the two molecules.
- Hydrolysis is the cleavage of the bond between two molecules by the addition of a water molecule.
- When hydrolysis of polypeptide takes place, there is a cleavage between the peptide bonds of amino acids.
- Each cleavage releases 2 molecules of amino acids.
- Polypeptide made of 3 amino acids will require 2 molecules of water.
- Hence, hydrolysis of 23 amino acids will require 22 water molecules.
