Deacylation refers to the process of removing an acyl group from a molecule, and there are several synonyms that can be used to describe this reaction. One alternative term is deesterification, which is often used in the context of hydrolysis reactions where an ester bond is cleaved. Another synonym is hydrolysis, which describes the breakdown of a molecule using water as a reactant. Deprotonation is another term that can be used to describe deacylation, as it involves the removal of a proton from the acyl group, leading to its removal from the molecule. Finally, decarboxylation can also be considered a synonym of deacylation, as it involves the removal of a carboxyl group from a molecule.
