(A) Measured and fitted carbon-nitrogen MMIDs of adenosine diphosphate (ADP) after 24h culture in labeled medium. Complete MMIDs are shown as array plots, selected isotopomers as bar charts. (B) Schematic of purine synthesis with fitted MMIDs. Percentages indicate relative contribution of pathways according to model estimates. (C) Measured and fitted carbon-nitrogen MMIDs of uracil diphosphate-glucose (UDP-glucose) after 24h culture in labeled medium. (D) Schematic of pyrimidine synthesis, as in B.
