MetaboAnalyst Pathway Enrichment

Perform metabolite pathway enrichment analysis (over-representation analysis) using hypergeometric test. Maps metabolite names to KEGG compound IDs, then tests which KEGG metabolic pathways are statistically enriched for the input metabolites. Returns pathways ranked by p-value with fold enrichment, FDR correction, and hit metabolites. Use for: identifying dysregulated metabolic pathways from a list of differentially abundant metabolites.
