Representative GC/MS TIC chromatograms of urine samples from three groups. (a) Group A (thick yellow coating), (b) Group B (thick white coating), and (c) Group C (thin white coating). Selected significantly changed metabolites have been labeled in this study: (1) butanedioic acid, (2) propanoic acid, (3) acetic acid, (4) ethanedioic acid, (5) butanoic acid, (6) glycine, (7) 2,3-dihydroxybutanoic acid, (8) aminomalonic acid, (9) cysteine, (10) benzoic acid, (11) D-mannose, (12) sedoheptulose, (13) D-gluconic acid, (14) myo-inositol, (15) tryptophan, (16) pseudouridine, and (17) α-D-glucopyranoside.
