amphipathic molecules

Amphipathic molecules have two distinct parts: one that is attracted to water (hydrophilic) and another that repels water (hydrophobic). This unique structure allows them to interact with both water and fats. A common example is phospholipids, which form cell membranes. The hydrophilic head faces outward toward water, while the hydrophobic tails face inward, creating a barrier that helps regulate what enters and exits the cell. This property is crucial for the structure and function of biological membranes, influencing everything from cell communication to nutrient transport.
