Metabolomics Pathway Analysis Identify metabolites, map to metabolic pathways, find disease associations, and connect to enzymes/genes. Domain Reasoning Metabolite-to-pathway mapping requires correct, database-specific identifiers. HMDB IDs link to KEGG/Reactome but must be converted via BridgeDb; PubChem CIDs need explicit cross-referencing. Always verify metabolite identity first: the same common name can refer to structurally distinct isomers, and PubChem names frequently differ from CTD/KEGG names. LOOK UP DON'T GUESS - Pathway membership: call , , or - Cross-database IDs: use - Enzyme-me…
