Lipids are commonly formed from which two components?

• A. Fatty Acids and Glycerol
• B. Glucose and Fructose
• C. Nucleotides and Sugars
• D. Amino Acids and Glycerol

Answer: (A)

Lipids are built from fatty acids and glycerol. Glycerol provides a three-carbon backbone that can form ester bonds with fatty acids; when three fatty acids attach, a triglyceride forms, which is a common storage lipid. The other options involve building blocks for other biomolecules (carbohydrates from sugars, nucleic acids from nucleotides, proteins from amino acids), not lipids.
