Sandwich (Davson–Danielli) model of cell membrane

Sandwich (Davson–Danielli) model

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 and it … Read more

Fluid mosaic model of a cell membrane

The plasma membrane, also known as the cell surface membrane or plasmalemma, defines the boundary of the cell. They are a special type of membranes which are lipid structures that … Read more
