Histogram showing differential metabolites annotated by comparisons to the Kyoto Encyclopedia of Genes and Genomes (KEGG) database. Differential metabolites were classified by KEGG pathway enrichment and significance analysis. Fold enrichment is presented as the ratio of the number of metabolites assigned to the modified pathway by enrichment analysis to the theoretical number of metabolites assigned to the modified pathway by random distribution. The degree of enrichment is indicated by different colors in the histogram, according to the p value. Histogram (A) shows DP9 versus DP0, histogram (B) shows DP12 versus DP0, whereas histogram (C) shows DP15 versus DP0
