The fluid mosaic model was used to explain the structure of the cell membrane. This model was well accepted model and given by Singer and Nicolson.
According to this model, the cell membrane is composed of lipids and proteins. The lipid layer is arranged and the proteins are inserted or span the bilayer. Some proteins are trans-membrane proteins, peripheral proteins and integral membrane proteins. Cholesterol are also inserted in this membrane. The carbohydrates are present in association with proteins or lipids on the cell membrane.
