Acetyl, chemical formula CH three CO - is a methyl and carbonyl Constitutive acyl group functional group 。

Acetyl is present in many compounds, including acetylcholine 、 Acetyl CoA 、 Acetaminophen 、 Acetylsalicylic acid （ aspirin ）, acetic acid, acetyl chloride Acetophenone , acetamide and acetic anhydride Etc. The chemical reaction of introducing acetyl groups into molecules is called acetylation reaction, and the corresponding reagents are called "acetylation reagents" and“ Acetyltransferase ”。 Under their action, acetylation can occur in coenzyme A Histone And other proteins.
