We developed a sensitive liquid chromatography-tandem mass spectrometry (LC-MS/ MS) method to simultaneously analyze the intracellular sugar phosphates dihydroxyacetone phosphate (DHAP), glyceraldehyde 3-phosphate, erythrose 4-phosphate, ribose 5-phosphate, ribulose 5-phosphate, xylulose 5-phosphate, fructose 6-phosphate, glucose 6-phosphate, and sedoheptulose 7-phosphate in blood spots.
