Select the correct statement regarding the structure and function of phospholipids.
Answer
They are amphipathic molecules that form the structural basis of biological membranes.
Explanation
Phospholipids are abundant membrane components and are amphipathic: fatty-acid regions are hydrophobic while the phosphate-containing region is more hydrophilic. The material describes fatty acids, a glycerol or sphingosine backbone, phosphate, and an attached alcohol as their components. **Key takeaway:** Amphipathic structure enables phospholipids to form membrane assemblies. **Glossary:** Amphipathic: containing both hydrophilic and hydrophobic regions.
