Match each lipid class with its defining structural feature: Lipid Classes: 1. Triacylglycerol 2. Wax ester 3. Glycerophospholipid 4. Sphingolipid Structural Features: A. Long-chain fatty acid esterified to a long-chain monohydric alcohol B. Three fatty acids esterified to a glycerol backbone C. Two fatty acids and a phosphate-linked polar head group attached to glycerol D. Fatty acid and polar head group attached to a sphingoid long-chain amino alcohol backbone
Answer
1-B, 2-A, 3-C, 4-D
Explanation
These classes are distinguished by their components and backbone. Triacylglycerols store energy; waxes are long-chain esters; glycerophospholipids use glycerol; and sphingolipids use sphingosine. **Key takeaway:** Lipid classification depends on molecular composition and backbone. **Glossary:** Ester: linkage formed between an acid and an alcohol.
