Which of the Following is a Feature of Membrane Proteins

Question

Which of the following is a feature of membrane proteins?
A)They have membrane-associated amino acids with polar side chains.
B)They are much more soluble in detergents than in water.
C)They have hydrophobic amino acids that are oriented inward.
D)They have a globular structure.

Accepted Answer

Membrane proteins are more soluble in detergents than in water because detergents can disrupt the lipid bilayer of membranes and solubilize the proteins, which often have hydrophobic regions that interact with the lipid bilayer. This property is used in laboratory techniques to isolate membrane proteins from cells or organelles.
