Isotopomic array representation of ¹³C enrichment in C-atom positions detected with ¹³C-NMR after [¹³C]Glc or [¹³C]pyruvate labeling of X. strumarium leaves in either H₂O or D₂O in the light under 400 μmol mol⁻¹ CO₂, 21% O₂, 400 μmol m⁻² s⁻¹ photosynthetically active radiation, and 21°C. Cit, Citrate; Cysth, cystathionine; Fum, fumarate; Icit, isocitrate; Mal, malate; Me-Glc, O-methyl-Glc; Myo, myoinositol; Pyr, pyruvate; Raf, raffinose; Succ, succinate; 2OG, 2-oxoglutarate. Fru is designated as Fru (pyranic form) or Fru-f (furanic form). Carbon atom positions are indicated with numbers. Suc-Glc indicates the Glc moiety of Suc, Raf-Glc indicates the Glc moiety of raffinose, and so on. Lowercase a and b indicate α- and β-configurations of hexoses, respectively.
