The factors that denature proteins include heat (high temperature and freezing at low temperature), exposure to acids or bases, and chemical change by denaturant. The heat denaturant of proteins is a phase of heat transition; the phenomenon has important biological implications.

We measured particle diameter and zeta potential in the context of phase transitions of bovine serum albumin (BSA) induced by heat by the light scattering method.
