Surfactant-driven modifications in protein structure

Area of Science:

• Biochemistry
• Materials Science
• Food Science

Background:

• Protein-surfactant interactions are extensively studied for applications in food, cosmetics, and medicine.
• Surfactants induce protein unfolding, with established models explaining the process and resulting structures.
• Physicochemical parameters like surfactant properties, protein characteristics, and solution conditions influence these interactions.

Purpose of the Study:

• To review the fundamentals and recent advancements in protein-surfactant interactions.
• To summarize the mechanisms of protein unfolding and refolding induced by surfactants.
• To explore the application of protein-surfactant interactions in directing heat-induced protein gelation.

Main Methods:

• Literature review of experimental and simulation studies on protein-surfactant interactions.
• Analysis of models describing protein unfolding and refolding mechanisms.
• Examination of studies utilizing protein-surfactant interactions for gelation control.

Main Results:

• Surfactants unfold proteins; refolding involves complex mechanisms, potentially forming mixed micelles.
• Protein-surfactant interactions can be leveraged to guide heat-induced protein gelation.
• Understanding physicochemical parameters is crucial for predicting and controlling interaction dynamics.

Conclusions:

• Protein-surfactant interactions are versatile, impacting protein structure and function.
• Further research into refolding mechanisms and gelation control is warranted.
• This interaction is a valuable tool for developing novel food and biomaterials.
