TIC obtained from the MRM screening mode of hydrophilic metabolites of the standards versus biological samples taken from C57BL/6 mice by UPLC-TQ MS. A. Overview of MRM chromatograms of the standards used: B. representative MRM spectra of metabolite standards glucose 6-phosphate, glutamine, alanine, choline and phenylalanine assessed; C. Corresponding MRM spectra of glucose 6-phosphate, glutamine, alanine, choline and phenylalanine from biological samples.
