We demonstrates a novel strategy to simultaneously measure metabolites pool sizes and kinetic constants of CK/ATPase reactions using 31P-MST spectroscopy. Our method enables the corrections for T₁ relaxation time and chemical exchanges effects due to short TR. The most important advantage of our proposed method is the reduction of TR for complete measurements of both metabolites ratios and reaction kinetics with high sensitivity. This can facilitate future applications requiring high temporal and/or spatial resolution.
