¹³C Labeling Kinetics of Metabolites from CBC, Starch, Suc, and Trehalose Biosynthesis Pathways.

(A) Time course of mass distribution. The relative abundance of each isotopomer (m_n) for a given metabolite is represented; n is the number of ¹³C atoms incorporated.

(B) and (C) ¹³C enrichment. The x axis corresponds to the labeling time on a log₁₀ scale. In (C), the y axis corresponds to ¹³C enrichments on a log₁₀ scale.

Values (%) are average of three biological replicates ± sd, with the exception of Suc6P and Tre6P at time 180 s (n = 1). For clarity, sds are not shown in (B) and (C).
