What is Hydrolysis?
Acid and Base: Acid–base-catalysed hydrolysis can be found during the hydrolysis of esters or amides. Here, the process of hydrolysis occurs when water or hydroxyl ion reacts with the carbon of the carbonyl group of the ester or amide where new compounds are formed. The products of both hydrolysis are compounds with carboxylic acid groups.
An Explanation of the Process of Hydrolysis
Hydrolysis reactions in living organisms are performed with the help of catalysis by a class of enzymes known as hydrolases. The biochemical reactions that break down polymers, such as proteins (which are peptide bonds between amino acids), nucleotides, complex sugars or starch, and fats are catalyzed by this class of enzymes. ...
