Comparative metabolomics analysis determines changes in gut metabolites
(A–D) The heatmap shows the difference between the gut metabolite profiles of EMPA and HFD mice (n = 3) in (A) positive ion mode and (B) negative ion mode. K-means analysis revealed the changed metabolites between the three groups in (C) positive ion mode and (D) negative ion mode.
