WebSep 27, 2024 · Phospholipids are composed of a glycerol and phosphate group (hydrophilic head) and two fatty acids (hydrophobic tails). Hydrophilic (water-loving polar) properties of phospholipids found in the head section attract water molecules and bind readily through hydrogen bonds. WebCholesterol has an OH group on one of its ends. Since the oxygen in the OH group is highly electronegative, it hogs all of the electrons and a positive charge is created on the hydrogen side of the group. That side then forms a hydrogen bond with the negatively charged oxygen on the phosphate group.
