WebA single phospholipid molecule has a phosphate group on one end, called the head, and two side-by-side chains of fatty acids that make up the lipid tails. The phosphate group is negatively charged, making the head polar and hydrophilic, or water loving. The phosphate heads are thus attracted to the water . What feature of fats makes them ... Web26 dec. 2024 · Phospholipids are amphipathic molecules. This means that they have a hydrophilic, polar phosphate head and two hydrophobic fatty acid tails. These components of the phospholipids cause them to orientate themselves, so the phosphate head can interact with water and the fatty acid tails can’t, hence forming a bilayer.
