Pathway analysis using all metabolites that were significantly different between the groups: (A) WS vs. WB (a) cysteine and methionine metabolism, (b) glutathione metabolism, (c) taurine and hypotaurine metabolism, (d) glycine, serine, and threonine metabolism, (e) glutamine and glutamate metabolism, (f) phenylalanine, tyrosine, and tryptophan biosynthesis; (B) NB vs. WS (a) taurine and hypotaurine metabolism, (b) nicotinate and nicotinamide metabolism, (c) aminoacyl-tRNA biosynthesis, (d) arginine and proline metabolism, (e) glycine, serine, and threonine metabolism, (f) β-alanine metabolism; (C) NB vs. WB (a) nicotinate and nicotinamide metabolism, (b) glycerophospholipid metabolism, (c) glycine, serine, and threonine metabolism, (d) arginine and proline metabolism, (e) β-alanine metabolism, (f) alanine, aspartate, and glutamate metabolism. The x-axis displays pathway impact values from the pathway topology analysis, and the y-axis the P-values from the pathway enrichment analysis. The darker the color, the more significant the pathway. Abbreviations: NB, normal breast; WB, wooden breast; WS, white stripping.
