asetilaation

Asetilaation is not a term with a single, widely recognized meaning in standard scientific nomenclature. It may be a misspelling, a transliteration variant, or a non-English term that corresponds to acetylation in some languages (for example, Indonesian 'asetilasi'). Because reliable sources do not define "asetilaation" as a distinct concept in chemistry or biology, the following describes the closely related and standard concept of acetylation.

Acetylation refers to the chemical introduction of an acetyl group, typically written as −COCH3, into a substrate. In organic synthesis, acetylation is used to protect reactive functional groups (such as hydroxyl or amine groups) during multi-step sequences or to modify reactivity. Typical reagents include acetyl chloride, acetic anhydride, and various acetylating agents, with conditions chosen to control selectivity and yield.

In biology, acetylation also denotes enzymatic processes that add acetyl groups to biomolecules. The best-known example is histone acetylation, which modulates chromatin structure and gene expression. This modification is carried out by acetyltransferase enzymes and removed by deacetylases, linking acetylation to regulation of transcription, metabolism, and signaling.

Applications span pharmaceutical development, polymer chemistry, and metabolic regulation. Acetylation can influence solubility, stability, and biological activity, making it a common tool in synthesis and analysis. In some languages or contexts, the term corresponding to acetylation is used as "asetilasi," which may be reflected in regional scientific vocabularies.
