Membrane models - Wikipedia
网页The Davson-Danielli model threw new light on the understanding of cell membranes, by stressing the important role played by proteins in biological membranes. By the 1950s, cell biologists verified the existence of plasma membranes through the use of electron microscopy (which accounted for higher resolutions).

5.2: Components and Structure - Fluid Mosaic Model
网页2023年10月31日 · The fluid mosaic model describes the structure of the plasma membrane as a mosaic of components —including phospholipids, cholesterol, proteins, and carbohydrates—that gives the membrane a fluid character. Plasma membranes range from 5 to 10 nm in thickness. For comparison, human red blood cells, visible via …

网页2014年12月19日 · Nowadays, the consensual model to depict the membrane structure and functions is called the “fluid mosaic model” [1]. The fluid mosaic hypothesis was formulated by Singer and Nicolson in the early 1970s [1]. According to this model, membranes are made up of lipids, proteins and carbohydrates (Figure 1).
