Functional Consequences of Lipid Packing Stress
When two monolayers of a non-lamellar lipid are brought together to form a planar membrane, the resulting structure is under elastic stress. This stress changes the membrane’s physical properties and, by modifying the energetics of hydrophobic inclusions, influences conformational equilibria of membrane proteins.
