(a) When mixed with water, phospholipids assemble themselves into a lipid bilayer with the polar head oriented inside and the nonpolar tail oriented outside. (b) While lipid bilayers constitute the main fabric of cell membranes, proteins and cholesterol are embedded in these membranes. (c) The two fatty acid side chains form the nonpolar tail and the phosphodiester group forms the polar head. (d) The phospholipid bilayer of cell membranes is also known as a fluid mosaic structure. (e) In the fatty acid tails of the lipid bilayer, the higher the degree of unsaturation, the better the bilayer packing, and the more rigid resulting cell membrane.
