WebMembrane lipids are a group of compounds (structurally similar to fats and oils) which form the double-layered surface of all cells (lipid bilayer).The three major classes of membrane lipids are phospholipids, glycolipids, and cholesterol.Lipids are amphiphilic: they have one end that is soluble in water ('polar') and an ending that is soluble in fat ('nonpolar'). WebAug 31, 2024 · Phospholipids are prevalent in the cells of bacteria and eukaryotes. They are molecules made of a phosphate head and a lipid tail. The head is considered water-loving or hydrophilic, whereas the tail is hydrophobic, or repellent to water. Phospholipids are therefore called amphiphilic.
