Web15 jul. 2024 · Cell membranes are incredibly complex. They are composed primarily of fatty-acid-based lipids and proteins. There are two types of these lipids: phospholipids and sterols - mainly cholesterol. Both lipids dissolve readily in organic solvents, and both have a region that is attracted to and soluble in water. Cell membrane can form different types of "supramembrane" structures such as caveola, postsynaptic density, podosome, invadopodium, focal adhesion, and different types of cell junctions. These structures are usually responsible for cell adhesion, communication, endocytosis and exocytosis.
