WebApr 17, 2024 · Amphiphilic describes a molecule which is part hydrophobic, part hydrophilic. There is often phosphorus atoms in the heads of the molecules, giving the heads polarity. The tails of the molecules are nonpolar and hydrophobic. In the image below, the polar parts of the molecules are marked in red. Webphospholipid bilayer of the cell membrane Your cell membranes are made of phospholipid bi-layers. The polar heads (the round phospho parts) face the outsides and the non-polar tails (the lipids--remember that lipids are fats) face the middle of the membrane.
