Figure 6.

Abundance of amino acid-derived metabolites in the plasma of SLC6A19ko (red) and wt (green) mice on diets with low (LP), standard (SP), or high protein (HP) contents in the fasted state (n = 5). Amino acid-derived metabolites: (A) Phenyl acetate, (B) Indole-3-propionic acid, (C) Indole-3-lactic acid, (D) Indole-3-acetic acid, (E) 2-aminoadipic acid, (F) Cresol glucuronide, (G) 3-methyl-2-oxovaleric acid and (H) 2-hydroxybutyric acid. No significant differences (p-value of <0.05) were observed between the genotypes. The error bars represent $\overline{x}\pm SEM$ (n = 5 per group). p-values were calculated by ANOVA comparing within-group and between-group variances of the diet effects (diet) and genotype effects (gene).
