Detailed explanation-1: -All of the lipid molecules in cell membranes are amphipathic (or amphiphilic)-that is, they have a hydrophilic (“water-loving”) or polar end and a hydrophobic (“water-fearing”) or nonpolar end. The most abundant membrane lipids are the phospholipids.

Detailed explanation-2: -The hydrophobic nature of lipids stems from the many nonpolar covalent bonds. Water, on the other hand, has polar covalent bonds and mixes well only with other polar or charged compounds. Fats and oils are high-energy molecules used by organisms to store and transfer chemical energy.

Detailed explanation-3: -Lipids are hydrophobic means water hating. They are water insoluble. Lipids are non-polar molecules while water is polar molecule, so there is no way for water to attach to a lipid molecule. Instead, the non-polar lipids will bind to themselves, which is why oils and fats form droplets on the surface of water.

Detailed explanation-4: -Lipids are chemical substances that are nonpolar in nature. Because water is a polar molecule, they are only soluble in nonpolar solvents and insoluble in water.

Detailed explanation-5: -Lipids do not dissolve in water at all. This is because lipids belong to the category of molecules that are non-polar in nature. The ends of lipids do not carry any charge. As we know that water is considered to be a polar molecule in nature, hence, lipids do not dissolve in water.
