TextSentencer_T1 0-75 Sentence denotes 31P nuclear magnetic resonance-pH titrations of myo-inositol hexaphosphate.
TextSentencer_T2 76-234 Sentence denotes With the use of 31P n.m.r. spectroscopy, the separate pKa values of each of the six phosphoric monoester groups of myo-inositol hexaphosphate were determined.
TextSentencer_T3 235-471 Sentence denotes The range of hydrogen-ion concentrations covered extended from that required for the phosphonium salts to that for the full dodecyl anion, and the determinations were carried out in the presence of sodium and tetrabutylammonium cations.
TextSentencer_T4 472-622 Sentence denotes The pKa for each phosphate grouping in the transition from the free acid forms of each group to the monoanion form of each group was determined to be:
TextSentencer_T5 623-682 Sentence denotes 1.1, C-2; 1.5, C-1 and C-3; 2.1, C-4 and C-6; and 1.7, C-5.
TextSentencer_T6 683-740 Sentence denotes In the mono- to di-anion transition, the pKa values were:
TextSentencer_T7 741-813 Sentence denotes 6.85, C-2; 7.60, C-5; 5.70 and 12.0, C-1 and C-3; and 10.0, C-4 and C-6.
TextSentencer_T8 814-956 Sentence denotes These data and the appearance of the 31P hexaphosphate n.m.r. multiplet are discussed in terms of conformations of myo-inositol hexaphosphate.
