Proton-decoupled 31P-NMR spectra of perchloric acid extracts of sycamore cells grown at 22°C and 5°C. Cells were harvested 5 d after subculture at 22°C (a) and 20 d after subculture at 5°C (b). Peak assignments are as follows: ref, reference (methylphosphonate) used for quantification; glc-6-P, glucose 6-phosphate; fru-6-P, fructose 6-P; Pi, inorganic phosphate; GPC, glycerophosphocholine; UDP-glc, uridine-5'-diphosphate-α-D-glucose.
