Thermodynamic pair interaction parameters on various concentration scales

Article Abstract:

Derivations for the relationships of the conversions of thermodynamic pair interaction parameters on various concentration scales are given. Details of the comparison made between the free energy pair interaction parameters obtained from different measurement methods or conversions are discussed, which indicates that the values on the same concentration scale are in good agreement with each other.

Entropic and enthalpic contributions to the chair-boat conformational transformation in dextran under single molecule stretching

Article Abstract:

The entropic and enthalpic contribution to the chair-boat conformational changes occurring during the force-extension of single molecules of an axially linked polysaccharide (dextran) is examined. The contribution of entropy to the Gibbs energy of the conformational transformation is small, indicating that the click is largely enthalpic in nature.

Calorimetric unfolding of intramolecular triplexes: Length dependence and incorporation of single AT (right arrow) TA substitutions in the duplex domain

Article Abstract:

The melting behavior of double hairpin triplexes of the pyrimidine motif containing exclusively TAT base triplets as a function of salt concentration is investigated. The results indicate that their melting behavior is consistent with an enthalpy-entropy balance between duplex and triplex formation.
