Hydrolysis
... In other hydrolysis reactions such as hydrolysing the peptide links of amino acids only one of the products, the carboxylic acid product, has a
hydroxide group derived from the water. The amine product gains the remaining hydrogen ion.
Hydrolysis can be considered as the opposite of condensation , ...
