Question

Quizplus · Accepted Answer

Their function depends on the dual polarity of their molecules. Soaps, detergents, phospholipids, and channel-forming antibiotics all have amphipathic properties, meaning they contain both hydrophobic (water-repelling) and hydrophilic (water-attracting) parts. This dual polarity allows them to interact with both water and lipid molecules, which is crucial for their respective functions in cleaning, forming cell membranes, and transporting ions across membranes.
