acetylate
LowTechnical/Scientific
Definition
Meaning
To introduce an acetyl group into (a molecule or compound).
To perform or undergo a chemical reaction where an acetyl functional group (CH3CO-) is added to a substrate, such as a protein, alcohol, or amine, often altering its function or properties.
Linguistics
Semantic Notes
Primarily used in biochemistry, organic chemistry, and pharmacology. It denotes a specific, precise chemical transformation. The noun forms are 'acetylation' (the process) and 'acetyl' (the group).

Examples
By Part of Speech
verb
British English
- The enzyme will acetylate the lysine residues on the histone tail.
- Researchers sought to acetylate the salicylic acid to produce aspirin.
American English
- The lab protocol is designed to acetylate the compound at room temperature.
- This metabolite can acetylate cellular proteins, leading to toxicity.
adverb
British English
- The compound reacted acetylatingly under the given conditions (highly artificial).
adjective
British English
- The acetylated product was purified by column chromatography.
- Acetylated histones are associated with active gene transcription.
American English
- They analyzed the acetylated form of the protein via mass spectrometry.
- The acetylated derivative showed increased solubility.
Examples
By CEFR Level
- Scientists can acetylate proteins to study their function.
- Aspirin is made by a process that acetylates salicylic acid.
- The research demonstrated how the SIRT1 enzyme can deacetylate, and thus regulate, key metabolic transcription factors.
- In order to increase the drug's bioavailability, the team attempted to acetylate the polar hydroxyl group, rendering it more lipophilic.
Learning
Memory Aids
Mnemonic
Think of ACETYLATE as "add an ACETYL group" + the verb-making suffix '-ATE', as in 'activate'.
Conceptual Metaphor
CHEMICAL MODIFICATION IS TAGGING (The acetyl group is a chemical tag that changes the molecule's 'identity' or function).
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'ацетилировать' which is a direct cognate and correct. Ensure the context is chemical, not general 'to accelerate' or 'to accept'.
Common Mistakes
- Using it as a general term for 'change' or 'accelerate'.
- Misspelling as 'acetylate' (one 't') or 'acetylize'.
- Incorrect stress: /ˈæsɪtɪleɪt/ instead of /əˈsɛtɪleɪt/.

FAQ
Frequently Asked Questions
No, it is a highly specialised technical term used almost exclusively in chemistry, biochemistry, and pharmacology.
'Acetylate' is the standard, accepted term in scientific English. 'Acetylize' is non-standard and should be avoided.
The production of aspirin (acetylsalicylic acid) involves the acetylation of salicylic acid. Also, the acetylation of histone proteins in cells is a key mechanism for regulating gene expression.
The process is called 'acetylation'. The resulting compound can be described as an 'acetylated' derivative or an 'acetate' (if referring to the ester).
