acylation
Very LowTechnical/Scientific
Definition
Meaning
A chemical reaction that introduces an acyl group (RCO–) into a molecule.
The process of transferring an acyl group from one compound to another, a fundamental reaction in organic synthesis and biochemistry.
Linguistics
Semantic Notes
Refers specifically to the process or result of acyl group introduction. The term is almost exclusively used within chemistry and biochemistry contexts.

Mnemonic
Think: ACYL-ation = Adding an ACYL group (like in acetyl-CoA) to another molecule.
Conceptual Metaphor
Chemical handshake (transferring a functional group from one molecule to another).
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'acclimatisation' (акклиматизация).
- The '-ation' suffix corresponds to '-ация' (ацилирование), not '-изация'.
Common Mistakes
- Misspelling as 'acelyation' or 'acilitation'.
- Using it as a verb ('to acylate' is the verb form).

FAQ
Frequently Asked Questions
No. Acetylation is a specific type of acylation where the acyl group transferred is the acetyl group (CH3CO–). Acylation is the broader term for transferring any acyl group (RCO–).
The verb form is 'to acylate'. 'Acylation' is the noun form describing the process or result.
Primarily in organic chemistry, biochemistry, medicinal chemistry, and chemical engineering.
No, it is a highly specialised technical term unknown to the general public and only used by professionals in specific scientific fields.
