Explanation:
Detailed explanation-1: -Phospholipids can be described as amphipathic ("amphi” means “both"), because they have this dual nature (part polar and part non-polar). This characteristic causes phospholipids to self-associate into large macromolecular complexes in an aqueous (watery) environment.
Detailed explanation-2: -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.
