DSC studies of melting process of annealed native structures and postdenatured ones in low-amylose starches with different
degrees of hydration were carried out. The starch recrystallization at different thermal treatments of the samples was studied
both after the complete and partial destroy of native structures. It has been shown that native structures as well as postdenatured
ones possess the ability to perfection, which is most clearly seen at the annealing at temperatures inside their melting ranges.
The results obtained demonstrate that at the same duration of annealing the process of crystal perfection for secondary starch
structures proceed more intensively compared to the native ones. The presence of the remained native structures in partial
melt in contrast to the remained gel ones restricts the ability of the recrystallized structures to perfection. 相似文献

Quantum chemistry methods require various linear algebra routines for symmetric matrices, for example, diagonalization or Cholesky decomposition for positive matrices. We present a small set of these basic routines that are efficient and minimize memory requirements. 相似文献

By method of differential scanning calorimetry the absolute values of heat capacity for the systemwater–biopolymer (globular
and fibrillar proteins and DNA) were measured in a wide range of temperatures (from -30 up to 130°C) and concentrations of
proteins both in native and denatured states. Thermal properties of humid denatured biopolymers demonstrate a characteristic
anomaly in the form of the heat capacity jump at temperature depending on the bound water content. It has been shown that
in the systems studied a glass transition, where water serves as a native plasticizer, is observed. It has been established
that the S-shaped character of all heat capacity curves obtained on dehydration for native and denatured biopolymers is due
to the gradual transition to the glassy state of both native and denatured samples. It was found that thermally denatured
humid small globular proteins at subsequent dissolving in water at room temperature are able to restore their native structure.

The temperature dependences of heat capacity for water–denaturated biopolymer (globular proteins, collagen and DNA) were measured
in a wide range of temperatures (0–140°C) and water content of the systems. It has been shown that thermally denaturated globular
proteins (lysozyme, myoglobin and catalase) are able to form the thermoreversible heat-set structures under the certain conditions
studied. The additional endothermal maximum observed is the calorimetric manifestation of the phase transition related to
the melting of these thermotropic non-native structures. The melting gels are completely formed just after denaturation during
relatively short time and only their prolonged state at T>T
d leads to their transformation to thermoirreversible non-melting ones. The post denaturated structures from water-denaturated
protein (Mb, Lys and RN-ase) systems with a different amount of free water were also studied. The thermoreversible cold-set
gels are formed from both water-denaturated DNA and water-denaturated collagen systems. These thermotropic structures are
metastable. A spatial gel network of both collagen and DNA is formed from the native-like renaturated structures.

DSC study of native and denatured biopolymers with different chemical and steric structure was carried out in a wide range
of temperatures and water contents. It was shown that all the native and denatured humid biopolymers studied are glassy systems.
The residues of native structures surviving after partial dehydration prevent the glass transition at the glass transition
temperatures of the denatured biopolymers. In dehydrated native biopolymers the processes of melting and glass transition
take place in the same temperature range that leads to a large change of the heat capacity across denaturation. 相似文献
