An Explanation of the Process Hydrolysis

In a hydrolysis reaction involving an ester link, such as that found between two amino acids in a protein, the molecule is split. The resulting product is a split of the water molecule (H 2 O) into an OH and an H+ that form a hydroxyl (OH) group, and another that becomes a carboxylic acid with the addition of the remaining hydrogen proton (H+).
