FIG. 2.

¹³C-NMR spectra of excreted end products of [1-¹³C]glucose or [U-¹³C]glucose metabolism by bloodstream form T. theileri. Incubations were performed in RPMI medium containing either 10 mM d-[1-¹³C]glucose (panel A) or 10 mM d-[U-¹³C]glucose (panel B). Resonance peaks of carboxyl-groups (COOH) and methyl-groups (CH₃) were detected between 170 and 190 ppm and 16 and 30 ppm, respectively. Peaks marked by a question mark are minor unidentified end products. The asterisks indicate peaks that are also present in the blank incubations. Abbreviations: Ace, acetate; Ala, alanine; Lact, lactate; Succ, succinate.
