RHEOLOGICAL AND THERMAL PROPERTIES OF MASA AS RELATED TO CHANGES IN CORN PROTEIN DURING NIXTAMALIZATION.
(2013-02-19)
Traditional nixtamalization process produces a masa (dough) with appropriate cohesiveness and adhesiveness. Masa is considered as a network of solubilized starch polymers with dispersed, uncooked and swollen starch granules, ...
Thermal Versus High Hydrostatic Pressure Treatments on Calcium-added Soybean Proteins. Protein Solubility, Colloidal Stability and Cold-set Gelation
(Springer, 2019-03)
The effects of thermal treatment (TT) and high hydrostatic pressure treatment (HHPT) on calcium-added soybean protein 1% (w/w) aqueous dispersions at pH 7.0 were compared. High hydrostatic pressure, but not thermal treatment, ...
Effects of pH and Salt Concentration on Stability of a Protein G Variant Using Coarse-Grained Models
(2018-01-09)
The importance of charge-charge interactions in the thermal stability of proteins is widely known. pH and ionic strength play a crucial role in these electrostatic interactions, as well as in the arrangement of ionizable ...
Characterization of soybean proteins-fatty acid systems
(Springer, 2010-05)
This study investigated, with the aim of obtaining more flexible and hydrophobic proteins, the attachment of a low chain fatty acid, decanoic acid, to alkaline and acid soybean proteins; and the effect on their conformational ...
Molecular basis of thermal stability in truncated (2/2) hemoglobins
(Elsevier Science, 2014-04)
Background: Understanding the molecular mechanism through which proteins are functional at extreme high and low temperatures is one of the key issues in structural biology. To investigate this phenomenon, we have focused ...
Enzimas termoestáveis: fontes, produção e aplicação industrial
(Sociedade Brasileira de Química, 2007-02-01)
REVIEW: Living organisms encountered in hostile environments that are characterized by extreme temperatures rely on novel molecular mechanisms to enhance the thermal stability of their proteins, nucleic acids, lipids and ...

“Structural characterization of protein isolates obtained from chia (Salvia hispanica L.) seeds”
(Elsevier Science, 2018-04)
Chia protein isolates (CPI) were obtained through isoelectric precipitation under two different conditions in order to compare their structural properties. Extraction was carried out at pH 10 or 12, whereas precipitation ...
PEG-induced molecular crowding leads to a relaxed conformation, higher thermal stability and lower catalytic efficiency of Escherichia coli β-galactosidase
(Elsevier Science, 2015-12)
Enzymatic activities were historically assayed in dilute solutions where molecular crowding, molecular confinement and their consequences were not taken into account. Here we report how macromolecular crowding tunes catalytic ...
