Extended Figure 6. Intensities of isotopologues of metabolites (lactic acid, glutamate, asparagine, and taurine) produced from ¹³C515N₂-labeled glutamine in vitro and illustration of the corresponding pathways through which these metabolites are produced.

Metabolites with isotopologues shown are written in red. Other important intermediate metabolites are written in black. Non-labeled ¹²C and ¹⁴N are shown as black-filled circles while labeled ¹³C are shown as red-filled circles and labeled ¹⁵N are shown as green-filled circles. Raw intensities are normalized by both the protein concentration. Data are shown as mean ± s.e.m. (n = 5 for biologically independent samples, P values from unpaired t test, two-tailed).
