Phospholipid is an amphipathic molecule — it has both hydrophobic and hydrophilic parts (this you understand very well). The hydrophobic part is a long chain of hydrocarbon (hence tail) whereas the hydrophilic part is a small but highly polar region (hence head).

Phospholipids - Structure, Types, Properties and Function

WebAnswer: Because phospholipids have a polar head (the phosphate) and a nonpolar tail (the lipids), they are amphipathic. This means that they are part hydrophilic and part hydrophobic. Thus, if you drop phospholipids in water, often they will group up in beads called micelles. This is a special a... WebSince a lipid molecule contains regions that are both polar and nonpolar, they are called amphipathic molecules. The most abundant class of lipid molecule found in cell membranes is the phospholipid. The phospholipid molecule's polar head group contains a phosphate group. It also sports two nonpolar fatty acid chain groups as its tail. WebJun 8, 2024 · A phospholipid is an amphipathic molecule which means it has both a hydrophobic and a hydrophilic component.
