How many water molecules would be produced in making a polyp

How many water molecules would be produced in making a polypeptide that is 14 amino acids long?

Solution

One molecule of water is produced with the formation of one peptide bond. A peptide bond holds two amino acids, so a polypeptide chain of 14 amino acids are made up of thirteen peptide bonds. So 13 water molecules would be produced in making a polypeptide that is 14 amino acids long.
