ChEBI is a chemical database and ontology that is widely used to annotate biological data. Here, we show a tool that is currently in development that allows exploration of the biological annotations for metabolites that are found to be enriched in metabolomics investigations. This tool will be made available online soon.

  • ChEBI is manually curated. Chemicals are given a structure-based classification and assigned with the has_role relationship to the role ontology.
