1. What is acetylation? Into what general class of reactions does acetylation fall?

Acetylation (or in IUPAC nomenclature ethanoylation) describes a reaction that introduces an acetyl functional group into a chemical compound ... A reaction involving the replacement of the hydrogen atom of a hydroxyl group with an acetyl group (CH3 CO) yields a specific ester, the acetate.

It is a chemical reaction transferring an acetyl group from a donor molecule, acetyl-CoA, to the target protein or peptide. It could be classified as an anabolic reaction.

Explanation:

Hello,

Acetylation is a majorly presented biochemical reaction which is widely known as a cotranslational reaction that requires acetyl-CoA and is catalyzed by an acetyltransferase associated with the ribosome. Biochemically speaking, acetylation of targets (majorly proteins and peptides) is believed to be mediated by an acetyl transferase, which catalyzes the transfer of an acetyl group from a donor molecule, acetyl-CoA, to the target protein or peptide. Bringing this into bear, such acetylation falls into the biochemical reactions class of reactions, more specifically into the anabolic reactions, since an acetyl group is being transferred.

Best regards.
