Calorimetric techniques applied to the thermodynamic study of interactions between proteins and polysaccharides

Técnicas calorimétricas aplicadas ao estudo termodinâmico das iterações entre proteínas e polissacarídeos

ABSTRACT:

The interactions between biological macromolecules have been important for biotechnology, but further understanding is needed to maximize the utility of these interactions. Calorimetric techniques provide information regarding these interactions through the thermal energy that is produced or consumed during interactions. Notable techniques include differential scanning calorimetry, which generates a thermodynamic profile from temperature scanning, and isothermal titration calorimetry that provide the thermodynamic parameters directly related to the interaction. This review described how calorimetric techniques can be used to study interactions between proteins and polysaccharides, and provided valuable insight into the thermodynamics of their interaction.

Key words:
isothermal titration calorimetry; differential scanning calorimetry; calorimetric techniques; biomolecules; proteins.
