The corresponding isotopomer

of each molecule is illustrated next to the experimental data (mass spectra). White circles represent 12C whereas black circles indicate labelled 13C. The numbers given reflect the position of the carbon atom within the molecule. PEPCk: phosphoenolpyruvate carboxykinase; PPDK: see more pyruvate-orthophosphate dikinase.
