Detailed explanation-1: -Amphipathic molecules are chemical compounds that have both polar and nonpolar regions, giving them both hydrophilic (water-loving) and lipophilic (fat-loving) properties. Amphipathic molecules are also known as amphiphilic molecules or amphiphiles.
Detailed explanation-2: -Amphipathic molecules have both polar and nonpolar sections. For phospholipids, the phosphate region carries a negative charge, making it polar, while the lipid tail is a nonpolar hydrocarbon. Being amphipathic is a key characteristic that allows phospholipids to form the plasma membrane.
Detailed explanation-3: -Amphiphiles are compounds possessing both hydrophilic (water-loving) and lipophilic (fat-loving) or water-hating components. In conventional head/tail(s) amphiphiles the lipophilic part consists generally of a long (saturated or unsaturated) hydrocarbon chain, while the hydrophilic head can be either nonionic or ionic.
Detailed explanation-4: -A molecule with both a polar and non-polar parts is known as amphipathic. The word amphoteric means a molecule that can act as either an acid or a base. Finally, just as a fatty acid has both polar and non-polar ends, those same ends are also hydrophilic and hydrophobic, respectively.
