Analysis of pathway related to fecal differential metabolites. KEGG topology analysis on the differential metabolites of the NC group vs. Model group (A), XKY-H group vs. Model group (B). C Schematic illustration of arginine metabolism, alanine, aspartate and glutamate metabolism, phenylalanine, tyrosine and tryptophan biosynthesis, and tryptophan metabolism by fecal untargeted metabolomics from NC, Model and XKY-H treatment groups. These four pathways are affected in both Model vs. NC and XKY-H treatment vs. Model groups. These metabolites are closely related to each other and the previous literatures reported relationships between each metabolite were showed in black arrows
