Question
Why do detergents extract soluble and membranous material from cells?

Answer
The structure of detergents is very similar to the lipids that form the bilayer cell membrane. Detergents and these lipids both have a hydrophobic (doesn't like to bind to water) tail and a hydrophobic (likes water) head. When detergents come into contact with cells, the detergents can mix with the lipids in the cell membrane thereby breaking up the cell layer. Detergents often end up mixing with the membrane lipids and forming their own little spheres, called micelles, with the hydrophilic heads on the outside and their tails all on the inside, away from the water. Hope this helps!

Expertise

PhD student in Biological Sciences at Northwestern U. I can answer questions related to cell and molecular biology, especially those about the basic processes or techniques involved in the life of a cell. I can also answer questions about insulin receptors, since that is my area of expertise. I have a great interest in how scientific discoveries impact society so feel free to ask me about current "hot" science topics in the news and I will try to researcha and share with you the most relevant facts.
