the interaction of hgh with some metal ions ( ) at 27°c in nac1 solution, 50 mm was studied using isothermal titration calorimetry. there is a set of three identical and non-interacting binding sites for binding of all these metal ions, expect . the intrinsic association equilibrium constants () are not very different for  and , and also their molar enthalpies of binding (kj/mol for  and  kj/mo...

thermodynamic study on the interaction of β-cd with poly ethylene oxide and poly acrylic acid was performed by isothermal titration calorimetry at 298k. when β-cd is added to the interpolymer complex, competition is created between host-guest and hydrogen bond. enthalpy of interaction between the β-cd and interpolymer complex was calculated using the extended solvation theory. p=1 shows that wi...

Enzymes, the catalysts of biological systems, are remarkable molecular devices that determine the patterns of chemical transformations. For many decades, a great deal of pure and applied studies have been devoted to enzyme reactions, as the mechanisms underlying the special characteristics of the reactions, such as high specificity and high efficiency, have not only attracted scientific interes...

Isothermal titration calorimetry is presented to be an excellent method of detecting lipid membrane solubilization upon the addition of detergents. As an example, the titration of the nan-ionic detergent C t2EOt, to the lipid POPC is studied. The main contribution to the measured titration heat is the detergent's enthalpy difference upon transfer between micelles and membranes. The detergent ad...

By use of isothermal titration calorimetry (ITC) and ultrasensitive differential scanning calorimetry (US-DSC), we have investigated the energy change in the periodic swelling-to-deswelling of thermally sensitive poly(N-isopropylacrylamide) (PNIPAM) microgels containing ruthenium(II) tris(2,2'-bipyridine) (Ru(bpy)3) which is a catalyst for Belousov-Zhabotinsky (BZ) reaction. As temperature incr...
