Fig. 10. ³¹P NMR chemical shifts for the Mg²⁺–Ins(1,3,4,5,6)P ₅ system as a function of pH in 0.15 M NMe₄Cl at 37.0 °C. [Ins(1,3,4,5,6)P ₅] = 2.5 mM, [Mg²⁺] = 1.0 mM. The solid lines show the HypNMR expected chemical shifts, according to the adjusted constants given in Table 1. For comparison, the chemical shifts for the ligand in the absence of cations are also shown.
