Acetylation is the process of reacting an organic compound with acetic acid to produce an ester and water. Acetylation is one of the most common reactions in organic chemistry. Acetylating agents, such as acetic anhydride or acetyl chloride, are often used in chemical synthesis because they react selectively with primary and secondary alcohols to form esters. The acetylation reaction can be used to modify proteins by attaching an acetyl group to the amine group of a lysine residue. This modification prevents the protein from binding to other proteins and can alter its function. Acetylation also has been implicated in several diseases, such as hepatitis and inflammatory bowel disease.
