About this source
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 the source is connected.
“Look up a compound by name or CAS number and list its structure, properties and hazard statements.”
What comes back: The database record with identifiers (InChIKey, CID) and a link to verify it at the source.
What the assistant can do with it
The 2 tools this server offers to Kahubi. The assistant picks the right one for each question.
chebi_searchSearch ChEBI, the curated dictionary of chemical entities of biological interest.
chebi_classificationParent classes of a ChEBI entity (what it "is a"): e.g.
Good to know
- 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.
