the thermal denaturation of α-amylase from bacillus amyloliquefaciens has been investigated in the presence and absence of sodium dodecyl sulphate (sds) over the temperature range (293-373) k in 20 mm sodium phosphate buffer, ph 6.9, using temperature scanning spectroscopy. the presence of sds caused the destabilization of α-amylase resulting in a decrease in the temperature of unfolding with a...

one of the methods to enhance bio-accessibility of drugs like acridone and its oxime is toform inclusion complexes with β-cyclodextrin. the formation of such complexes has beenconfirmed by changes in spectral characteristics and melting point data. the aqueous phasesolubility studies reveal 1:1 stoichiometry between the compound and, β-cyclodextrin. the studyof thermodynamic parameters like δg,...

In the framework of a lattice-model study of protein folding, we investigate the interplay between designability, thermodynamic stability, and kinetics. To be \protein-like", heteropolymers must be thermodynamically stable, stable against mutating the amino-acid sequence, and must be fast folders. We nd two criteria which, together, guarantee that a sequence will be \protein like": i) the groun...

The thermodynamic formalism for rotating black holes, characterized by noncommutative and quantum corrections, is constructed. From a fundamental thermodynamic relation, the equations of state and thermodynamic response functions are explicitly given, and the effect of noncommutativity and quantum correction is discussed. It is shown that the well-known divergence exhibited in specific heat is ...

The stability of the recently characterized type II hydrogen clathrate [Mao, W. L., Mao, H.-K., Goncharov, A. F., Struzhkin, V. V., Guo, Q., et al. (2002) Science 297, 2247-2249] with respect to hydrogen occupancy is examined with a statistical mechanical model in conjunction with first-principles quantum chemistry calculations. It is found that the stability of the clathrate is mainly caused b...
