From a Structural Standpoint, Integral Membrane Proteins are Most Similar

Question

From a structural standpoint, integral membrane proteins are most similar to which membrane lipids?
A) cholesterol
B) phospholipids
C) neutral lipids
D) polyunsaturated fatty acids.
E) none of these.

Accepted Answer

Integral membrane proteins share a structural similarity with phospholipids in that both have hydrophobic regions that interact with the lipid bilayer and hydrophilic regions that interact with the aqueous environment, allowing them to be embedded within the cell membrane.
