Amphipathic

Definition

Amphipathic molecules possess both hydrophilic (water-attracting) and hydrophobic (water-repelling) regions, allowing them to interact with both water and lipid environments. This dual characteristic is crucial for the structure and function of cell membranes.

Related terms

Hydrophilic: Pertains to molecules or portions of molecules that are attracted to water and can form hydrogen bonds with water.

Hydrophobic: Describes molecules or parts of molecules that avoid water and tend not to dissolve in it, typically because they are nonpolar.

Phospholipid Bilayer: A double layer of phospholipid molecules that form the primary structure of all cell membranes, featuring hydrophilic heads facing outward and hydrophobic tails facing inward
