About ChEBI (chemical ontology)
EMBL-EBI’s ontology of chemical entities of biological interest. Get the curated definition of a compound or a compound class, its IUPAC and common synonyms, and walk the classification upwards (ibuprofen is a monocarboxylic acid). Useful for precise terminology in a manuscript.
Questions you can ask ChEBI
Type them into Kahubi’s chat once ChEBI is connected.
“Give me the ChEBI definition of resveratrol and the classes it belongs to.”
What comes back: The ChEBI id, definition, IUPAC name and synonyms, then its parent classes up the ontology.
“Is caffeine classified as a purine alkaloid in ChEBI?”
What comes back: The classification path for caffeine with ChEBI ids, so the terminology in a manuscript is exact.

Using ChEBI in Kahubi
- Hosted by Kahubi. Kahubi runs this server itself so it stays reliable enough for research use.
- Cited, checkable answers. Results are treated as retrieved material and cited with the source’s own identifiers, so you can open every record the answer relied on.
- Your files stay private. Only the search the assistant writes for your question is sent to ChEBI.
