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.

  • Recent addition: ‘Metabolite of Species’
  • MetaboLights – a repository formetabolomics experiments
  • Metabolites identified in study linked to ChEBI

  • How does chocolate lead to Nobel prizes?
  • Ontology enrichment analysis for chemicals inmetabolomics result based on ChEBI roles
  • Chemical—GO enrichment (uses GO-ChEBI XPs)
  • Chemical role enrichment for metabolites identifiedin bipolar disorder metabolomics study Annotation density increases quality of enrichment results ChEBI cross-references can be adapted to be used as sources of annotations
