Layers of a cell membrane
Web31 jul. 2024 · The cell membrane is known as a trilaminar cell membrane or the trilaminar model because it consists of a layer of hydrophobic tails of phospholipids sandwiched between two layers of hydrophillic heads. Often, however, it is called a bilayer, because it is made of two sets of phospholipids. Web17 mei 2024 · The cell membrane consists of two adjacent layers of phospholipids. The lipid tails of one layer face the lipid tails of the other layer, meeting at the interface of the two layers. The phospholipid heads face outward, one layer exposed to the interior of the cell and one layer exposed to the exterior ( Figure 2.2. 2 ).
