Figure 2

Summary of pathway analysis with MetPA. (a) Phenylalanine, tyrosine, and tryptophan biosynthesis, pathway impact: 0.50, (b) citric acid cycle, pathway impact: 0.39, (c) phenylalanine metabolism, pathway impact: 0.24, (d) sphingolipid metabolism, pathway impact: 0.14, and (e) tyrosine metabolism, pathway impact: 0.14. The node color is based on its value and the node radius is based on their pathway impact values.
