Figure 4. Selected regions of the 1H-NMR spectra of urine from each experimental group.

Figure 4

The singlet of the creatinine signal (4.05 ppm) and the doublet of the signal of hippurate (3.97 ppm) in the (A) Control group, (B) FAIG-Mi, (C) FAIG-Mo, (D) FAIG-S. The acetate singlet (1.92 ppm) in the (E) Control group, (F) FAIG-Mi, (G) FAIG-Mo, (H) FAIG-S. The n-1-methylnicotinamide doublets (8.89 and 8.99 ppm) in the (I) Control group, (J) FAIG-Mi, (K) FAIG-Mo, (L) FAIG-S. Visual differences are clearly detectable.
