A researcher is analyzing a lipid sample that provides a protective, water-repellent coating on plant leaves. Which component is uniquely absent in this wax compared to acylglycerols?
Q1. A researcher is analyzing a lipid sample that provides a protective, water-repellent coating on plant leaves. Which component is uniquely absent in this wax compared to acylglycerols?
Answer: Glycerol backbone
Explanation: Waxes lack glycerol, containing long-chain alcohols instead. Acylglycerols are tempting because they are common lipids, but they always contain a glycerol backbone.
