The Davson–Danielli model (or paucimolecular model) was a model of the plasma membrane of a cell, proposed in 1935 by Hugh Davson and James Danielli. The model describes a phospholipid bilayer that lies between two layers of globular proteins , which is both trilaminar and lipoprotinious. [ 1 ]
J. David Robertson used this method to propose the unit membrane model. [4] Basically, he suggested that all cellular membranes share a similar underlying structure, the unit membrane. Using heavy metal staining, Robertson's proposal also seemed to agree instantaneously with the Davson-Danielli model.
James Frederic Danielli FRS [1] (1911–1984) was an English biologist. He was famous for research on the structure and the permeability of cell membranes, developing a physical-chemical model in collaboration with the physiologist Hugh Davson. This became known as the Davson-Danielli [2] or "protein sandwich" model. He also carried out studies ...
With James Danielli he proposed a model for cell membrane structure which became known as the Davson-Danielli or "protein sandwich" model. In 1931 he married the society portrait painter Marjorie Heath with whom he had one daughter. He was a cousin of the renowned journalist and broadcaster, Alistair Cooke. [2]
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.
