The significant level of the metabolite correlation was set at p < 0.001. Only pairs comprising identified metabolites are listed. The metabolites were defined as those identified on comparison with mass spectra and retention indices (RIs) from the library databases (Golm Metabolome Database [30] and our own library) and with authentic standards. Abbreviations: Glycerol-3-P, glycerol-3-phosphate; Inositol-1-P, myo-inositol-1-phosphate; Adenosine-5-P, adenosine-5-monophosphate.
