Figure 4. KEGG metabolic pathway of differential metabolites in FF and GC. (A) KEGG pathway enrichment analysis of FF metabolites; (B) KEGG pathway enrichment analysis of GC metabolites. The vertical coordinate represents the corresponding pathway and the horizontal coordinate represents the impact value of the pathway. The size of the dot represents the number of differential metabolites in the target metabolic pathway, the larger the dot, the greater the number of metabolites enriched into that pathway. P-values are represented by color, the darker the color, the smaller the p-value.
