What is the difference between peripheral and integral protein membranes?

Answer 1

Like floating icebergs, peripheral proteins are only found on the inner or outer surfaces of the phospholipid bilayer, whereas integral proteins are embedded throughout the bilayer.

Peripheral proteins lack the hydrophobic and hydrophilic regions found in integral proteins.

Integral proteins are embedded within the lipid bilayer and can span the entire membrane or be partially embedded; they are firmly anchored to the membrane, whereas peripheral proteins are temporarily attached to the lipid bilayer or integral proteins, often through electrostatic interactions, and can easily detach from the membrane.
