Question

The nature of the lipid bilayer is
a. hydrophilic
b. hydrophobic
c. amphipathic
d. lipophilic

Answer 1

The nature of lipid bilayer is amphipathic,

Membrane lipids are Amphipathic molecules, most of which spontaneously form bilayers.

Amphipathic is a property of a molecule, especially a protein which is having properties of both hydrophilic and hydrophobic.

Hydrophilic means something which is water loving and needs water to sustain whereas hydrophobic means water fearing and these do not need water to sustain.

These properties are found in detergents or phospholipids of biological membranes.
