Acetylation vs. Acylation: What's the Difference?

Edited by Huma Saeed || By Sumera Saeed || Published on December 7, 2023
Acetylation is the process of adding an acetyl group (CH₃CO) to a molecule, while acylation is the broader process of adding an acyl group (RCO) to a molecule, where R can be any organic group.

Key Differences

Acetylation specifically involves the addition of an acetyl group, a two-carbon unit, to another molecule. Acylation encompasses a wider range of reactions, involving the addition of various acyl groups, which can vary in the length and complexity of the carbon chain.
