acylation
Let an agent explain acylation and its kinds, relay mechanisms and reagents from chemistry references, describe biological acylation including tRNA aminoacylation, and distinguish acylation from alkylation and other functionalisations.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain acylation and its kinds, relay mechanisms and reagents from chemistry references, describe biological acylation including tRNA aminoacylation, and distinguish acylation from alkylation and other functionalisations.
A chemical reaction that introduces an acyl group into a compound, typically by reacting an acyl chloride, anhydride or ester with an alcohol, amine or aromatic ring, as in Friedel-Crafts acylation, benzoylation and acetylation, and in biology the attachment of amino acids to transfer RNA in aminoacylation, the first step of protein synthesis, and the acylation of proteins and lipids; acylation is fundamental in organic synthesis, pharmaceuticals and metabolism.
What it is for: Introducing acyl groups in synthesis and biology.
It can be explain kinds and mechanisms; relay reagents and conditions; describe biological acylation; distinguish from alkylation.

- How should reference sources be linked?
- The registry entry has merged aliases naming specific reactions; should they be split off?
