Explanation:
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. These have a polar head group and two hydrophobic hydrocarbon tails.
Detailed explanation-2: -The characteristic that all lipids have in common is that they are nonpolar molecules, which means they do not dissolve in water. Oils are a common type of lipid. If you try to mix oil and water, they will not combine, and the oil will form its own layer on top of the water. This is true of all lipids.
