aThe formation of Glycerol-1,2-cyclic phosphate was observed after 24 h. However, this signal disappeared after heating for 167 h (see Supplementary Fig. 65).

bt = 0 h is after drying to paste.

cFor ribose and glucose, multiple peaks in the 31P-NMR spectra for phosphorylated sugars were observed (see Supplementary Fig. 135143). The yield quoted is the summation of integrals from all of these peaks.
