WebThe hydrophilic head is soluble in water due to it being charged or polar. This allows it to form electrostatic forces or hydrogen bonds with the water molecules. However, the hydrophobic tail is insoluble in water due to it being uncharged and non-polar meaning it cannot form any interactions with water molecules. The phospholipids are amphiphilic. The hydrophilic end usually contains a negatively charged phosphate group, and the hydrophobic end usually consists of two "tails" that are long fatty acid residues. In aqueous solutions, phospholipids are driven by hydrophobic interactions, which result in the fatty acid tails aggregating to minimize interactions with th…
