Pathway Analysis of Differential Metabolites
Enrichment analysis by KEGG pathway revealed that the differential metabolites may be involved in α-linolenic acid and linoleic acid metabolism, purine metabolism, homocysteine degradation, phosphatidylethanolamine biosynthesis, and so on (Fig. 4A). Similarly, the bubble chart of metabolic pathway analysis demonstrated that the differential metabolites were concerned with linoleic acid metabolism, phenylalanine metabolism, taurine, and hypotaurine metabolism, tyrosine and tryptophan biosynthesis (Fig. 4B).
