Background:

Detergents are crucial for solubilizing and studying membrane proteins.
The amphipathic nature of detergents leads to complex self-assembly and interactions.
Factors like concentration, ionic conditions, and co-existing lipids/proteins influence detergent behavior.

Purpose of the Study:

To review the diverse aggregate forms of detergents.
To address common misconceptions regarding detergent structures.
To highlight the importance of distinguishing detergents from native membrane lipids.

Main Methods:

Literature review of detergent properties and behavior.
Analysis of high-resolution membrane protein structures.
Discussion of detergent-lipid and detergent-protein interactions.

Main Results:

Detergents exhibit varied aggregate structures beyond simple micelles.
Misconceptions about detergent self-assembly and function persist.
Recent structural data emphasize differences between detergents and membrane lipids.

Conclusions:

Detergents are indispensable yet complex tools in membrane protein science.
Knowledge of detergent behavior is key to their successful application.
The expanding range of available detergents offers new opportunities for research.
