Schematic diagram of phenylalanine metabolism, tryptophan metabolism, glycine, serine and threonine metabolism, citrate cycle (TCA cycle), alanine, aspartate and glutamate metabolism, arginine and proline metabolism, pentose phosphate pathway, and their relevant differential metabolite alterations during DKD occuration. The upregulated metabolites in the DKD group were labeled with red and downregulated metabolites in the DKD group with blue.
