Pathways with differences in metabolite levels between the Amazon and Rio de Janeiro sample groups. Ions showing differences of at least 2-fold in relative intensity values between these groups were assigned to KEGG pathways using the Pathos online software. This was done for both positive (black bars) and negative (white bars) ionization data. Bars represent the number of assigned metabolites in each pathway. Only pathways that had at least 5 assigned ions are shown.
