WebMay 29, 2015 · The phospholipid has a polar, hydrophilic head and a nonpolar, hydrophobic tail. My question: Why doesn't the hydrophilic head dissolve in the extracellular fluid outside the cell? I suppose that the extracellular fluid is watery, so how come that the water-loving head doesn't interact with the water from the extracellular fluid? biochemistry WebDec 29, 2024 · The phosphate head is polar (water-soluble) and the tails are nonpolar (lipid-soluble), which makes the molecule amphiphilic (soluble in polar and nonpolar solvents).

WebPhospholipids are amphipathic molecules that make up the bilayer of the plasma membrane and keep the membrane fluid. The phosphate group is the negatively-charged polar head, … WebJun 11, 2024 · Phospholipids are basically complex lipids. Characteristically, a phospholipid molecule has a polar head group and a non-polar tail group. The fatty acid chains form the hydrophobic or lipophilic or non-polar tail whereas the esterified phosphate group forms the hydrophilic or polar head group. Hence, the question arises. highlander aftermarket accessories
