S. Ganguly et Kk. Kundu, DEPROTONATION ENERGETICS OF DISODIUM URIDINE 5'-MONOPHOSPHATE AND DISODIUM GUANOSINE 5'-MONOPHOSPHATE IN WATER FROM EMF-MEASUREMENTS, Indian journal of chemistry. Sect. A: Inorganic, physical, theoretical & analytical, 33(12), 1994, pp. 1099-1103
The second step and third step deprotonation constants of 5'-uridine m
onophosphate and 5'-guanosine monophosphate have been obtained in wate
r from emf measurements of Harned Ehler-type cells comprising H-2 and
Ag-AgI electrodes at different temperatures. The pK values have been f
itted in the temperature equation pK=AT(-1)+B+CT by least squares meth
od and the related thermodynamic quantities viz., Delta G degrees, T D
elta S degrees and Delta H degrees have been obtained using the values
of the coefficients A, B and C of the respective mononucleotides.
