The hydrophilic head group consists of a phosphate-containing group attached to a glycerol molecule. The hydrophobic tails, each containing either a saturated or an unsaturated fatty acid, are long hydrocarbon chains. WebApr 8, 2024 · Phospholipids are arranged in the bilayer structure with hydrophobic tails inside and hydrophilic heads outside the bilayer in an aqueous environment. The hydrophilic head molecule possesses charged or uncharged polar groups, which form electrostatic interactions or hydrogen bonds with water to make them readily dissolve in it. how did banting discover insulin
