Figure 2

Simulated 12C/13C isotopologues of 20 carbon metabolite. In all 3 charts, the red bars represent the relative isotopologue intensities with contributions (contamination) from 13C natural abundance. The green bars represent the corrected isotopologue intensities with this contamination removed. Chart A shows the expected isotopologues of a metabolite with no additional 13C-labeling present. Chart B shows the expected isotopologues of a metabolite with equal amounts of 13C-labeling for 8, 10, and 12 carbons. Chart C shows the expected isotopologues of a metabolite with 100% 13C-labeling.
