In organic chemistry, an acetyl group is a functional group denoted by the chemical formula −COCH3 and the structure −C(=O)−CH3. It is sometimes represented by the symbol Ac (not to be confused with the element actinium). In IUPAC nomenclature, an acetyl group is called an ethanoyl group.
An acetyl group contains a methyl group (−CH3) that is single-bonded to a carbonyl (C=O), making it an acyl group.
