Thermodynamics of the Hydrolysis Reactions of Nitriles

July 1, 2005
Author(s)
Yadu D. Tewari, Robert N. Goldberg
Microcalorimetry and high-performance liquid chromatography (h.p.l.c) have been used to conduct a thermodynamic investigation of the following nitrilase catalyzed reactions: (1) benzonitrile(aq) + 2 H2O(l) = benzoic acid(aq) + ammonia(aq), (2)

Saturation Molalities and Standard Molar Enthalpies of Solution of Cytidine(cr), Hypoxanthine(cr), Thymidine(cr), Thymine(cr), Uridine(cr), and Xanthine(cr) in H 2 O(1)

Saturation molalities, m(sat) in H 0(I) have been measure for the substances cytidine(cr), hypoxanthine(cr), thymidine(cr), thymine(cr), uridine(cr), and xanthine(cr) by using h.p.l.c. The states of hydration were established by performing Karl-Fischer

Thermodynamics of the Hydrolysis Reactions of Adenosine 3', 5'-(Cyclic)phosphate(aq) and Phosphoenolpyruvate(aq); the Standard Molar Formation Properties of 3',5'-(Cyclic)Phosphate(aq) and Phosphoenolpyruvate(aq)

November 1, 2003

Robert N. Goldberg, Yadu D. Tewari
Molar calorimetric enthalpy changes DrHm(cal) have been measured for the biochemical reactions1 {ATP(aq) = cAMP(aq) + pyrophosphate(aq)} and {cAMP(aq) + H2O(l) = AMP(aq)}. The reactions were catalyzed, respectively, by adenosine 3',5'-(cyclic)phosphate and

Thermodynamics of Enzyme-Catalyzed Reactions

March 1, 2003
Author(s)
Robert N. Goldberg, Yadu D. Tewari
This review, which has been prepared for the McGraw-Hill 2003 Yearbook of Science and Technology, gives an overview of the thermodynamics of enzyme-catalyzed reactions. Topics include the thermodynamic formalism(s) used in this field, computational methods

Thermodynamic Quantities for the Ionization Reactions of Buffers in Water

December 1, 2002
Author(s)
Robert N. Goldberg, N Kishore, R M. Lennen
This table contains selected values for the pK, standard molar enthalpy of reaction {Δ} rH , and standard molar heat-capacity change {Δ} rC p for the ionization reactions of 64 buffers many of which are relevant to biochemistry and to biology. The values

A Thermodynamic Study of the Reactions: 2-Dehydro-3Deoxy-D-Arabino-Heptanoate 7-Phosphate(aq) = {3-Dehydroquinate (ag) + Phosphate (aq)} and {3-Dehydroquinate(aq) =3-Dehydroshikimate(aq) + H 2 O(l)}

Yadu D. Tewari, Robert N. Goldberg, A R. Hawkins, H K. Lamb
Microcalorimetry and high-performance liquid chromatography (h.p.l.c.) have been used to conduct a thermodynamic investigation of reactions catalyzed by 3-dehydroquinate synthase and by 3-dehydroquinate dehydratase. These are the second and third reactions
