Hydrophilic region of cell membrane

WebThe polar hydrophilic head interacts with water from the extracellular environment and the intracellular cytoplasm. Meanwhile, the nonpolar hydrophobic tail forms a core inside the membrane as it is repelled by water. This is because the tail is comprised of fatty acid chains. As a result, a bilayer is formed from two layers of phospholipids. Web5 dec. 2024 · The hydrophilic regions of the phospholipids tend to form hydrogen bonds with water and other polar molecules on both the exterior and interior of the cell. Thus, the membrane surfaces that face the interior and exterior of the cell are hydrophilic. In contrast, the interior of the cell membrane is hydrophobic and will not interact with water.
