INS and Insulin resistance: According to the KEGG pathway enrichment analysis, D‐amino acid metabolism, tryptophan metabolism, steroid hormone biosynthesis, sphingolipid metabolism, pyrimidine metabolism, insulin signaling pathway, insulin resistance, glycine, serine, threonine metabolism, cAMP signaling pathway, and butanoate metabolism were considered to be the most important pathways between the SP and control group (Figure 5G).
