Proposed by Singer and Nicolson. This model is likened to integral membrane protein 'icebergs' floating in a sea of predominantly fluid phospholipid molecules. At normal body temperature (37 0 C) the lipid bilayer is in a fluid state. The longer and more saturated fatty acid chains cause higher values of transition temperature.
