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.
The mosaic crystal model goes back to a theoretical analysis of X-ray diffraction by C. G. Darwin (1922). Currently, most studies follow Darwin in assuming a Gaussian distribution of crystallite orientations centered on some reference orientation. The mosaicity is commonly equated with the standard deviation of this distribution.

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.
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 ...
Garth L. Nicolson (born October 1, 1943) [1] is an American biochemist who made a landmark scientific model for cell membrane, known as the fluid mosaic model.He is the founder of The Institute for Molecular Medicine at California, and he serves as the president, chief scientific officer and emeritus professor of molecular pathology.
The model proposed by John A. Greenwood and John H. Tripp (GT), [40] extended the GW model to contact between two rough surfaces. The GT model is widely used in the field of elastohydrodynamic analysis. The most frequently cited equations given by the GT model are for the asperity contact area
