  1. n.d.: Not detected.
  2. a Recovery rates from independent spiking experiments performed on an Orgueil matrix (Supplementary Note 3).
  3. b Values for arabinose and d-xylose represent the average ± standard deviation of four replicate injections, while other sugars were quantified from single injections due to signal deterioration in subsequent runs (Supplementary Fig. 10). Values uncorrected for procedural blanks.
  4. c Quantities after procedural blank correction.
  5. d Enantiomeric excess (ee) values were calculated from blank-corrected peak areas of both enantiomers in the single-ion chromatograms. Values for arabinose and xylose are based on four replicate injections, whereas those for ribose, lyxose, and ribulose are derived from the first injection only and are considered indicative.
  6. e The 13C enrichment was not significant or could not be analyzed in the original study by Furukawa et al.19.
