Letter to the editor: "Interpretation of (31)P NMR saturation transfer experiments: do not forget the spin relaxation properties".

to the editor: In an interesting Editorial Focus published last year in American Journal of Physiology-Cell Physiology , Balaban and Koretsky ([1][1]) drew attention to magnetization transfer (MT) effects that are observed in 31P magnetic resonance spectroscopy (MRS) experiments, in which the γ-ATP
