WebIn 1972, S. dessert apple Singer and Garth diplomatist developed the fluid-mosaic model of membrane structure. in line with this model, a membrane may be a double layer (bilayer) of proteins and phospholipids, and is fluid instead of solid. The lipoid bilayer forms a fluid “sea” during which specific proteins float like icebergs. WebThe principal components of the plasma membrane are lipids (phospholipids and cholesterol), proteins, and carbohydrate groups that are attached to some of the lipids and proteins.
