Estimated subcellular metabolite concentrations in mature celery leaves
| Metabolite | Chloroplast | Cytosol |
|---|---|---|
| mm | ||
| 3-PGA | 4.80 | 3.40 |
| ATP | 0.2 | 0.4 |
| Glc-6-P | 0.9 | 16.5 |
| Fru-6-P | 3 | 10.1 |
| Glc-1-P | 0.4 | 2.3 |
| NADP | 0.13 | 0.25 |
| NADPH | 0.09 | 0.24 |
Vacuole data are not shown since none of the metabolites were found in the vacuole at more than 2% of the totals. Although repeated several times, these estimates are the results from a single separation. The total metabolic pools were (in μmol g−1 dry wt) 3-PGA (4.2), ATP (0.15), Glc-6-P (3.2), Fru-6-P (2.6), Glc-1-P (0.6), and NADP(H) (0.29).
