Deacyl is a chemical term that refers to the removal of an acyl group from a compound. There are several synonyms for deacyl, including deacylation, decarbonylation, and desacylation. Deacylation is the most commonly used synonym, and it is often used interchangeably with deacyl. Decarbonylation, on the other hand, specifically refers to the removal of a carbonyl group from a compound. Desacylation is a less common synonym that specifically refers to the removal of an acyl group from a molecule. These synonyms are important for understanding the chemical processes involved in the modification of compounds, such as reactions in metabolism and drug metabolism.
