Fluid mosaic model of a cell membrane. The fluid mosaic model explains various characteristics regarding the structure of functional cell membranes.According to this biological model, there is a lipid bilayer (two molecules thick layer consisting primarily of amphipathic phospholipids) in which protein molecules are embedded.
Building on the fluid mosaic model, a framework called the proteolipid code was proposed in order to explain membrane organization. [8] The proteolipid code relies on the concept of a zone, which is a functional region of membrane that is assembled and stabilized with both protein and lipid dependency.
Of the numerous models that have been developed to describe the deformation of cell membranes, a widely accepted model is the fluid mosaic model proposed by Singer and Nicolson in 1972. [1] In this model, the cell membrane surface is modeled as a two-dimensional fluid-like lipid bilayer where the lipid molecules can move freely. The proteins ...

His seminal work on membrane proteins resulted in the development of the "Fluid Mosaic Model" of the cell membrane, published as "The Fluid Mosaic Model of the Structure of Cell Membranes", in Science in 1972. [3]
This model differs from older cell membrane structure concepts such as the Singer-Nicolson fluid mosaic model and the Saffman-Delbrück two-dimensional continuum fluid model that view the membrane as more or less homogeneous. The fences and pickets model was proposed to explain observations of molecular traffic made due to recent advances in ...
