Figure 4From: 13C labeling experiments at metabolic nonstationary conditions: An exploratory studySimulation of the isotopomer enrichments. The extracellular substrate Aex immediately switches from unlabeled to labeled. The enrichment of A and B is fast (steady state after <10 s), pool C shows intermediate labeling patterns before reaching the fully labeled steady state. These intermediate patterns can also be seen in D and E.Back to article page
