Which biomolecule class includes triglycerides?

Which biomolecule class includes triglycerides?

• A. Proteins
• B. Carbohydrates
• C. Lipids
• D. Nucleic acids

Answer: (C)

Triglycerides are a type of lipid. They are formed when a glycerol backbone bonds to three fatty acids, creating a large, nonpolar molecule that stores a lot of energy and is insoluble in water. This shows the defining trait of lipids: they are hydrophobic and excellent for long-term energy storage, as seen in fats and oils. While proteins are built from amino acids and perform functions like enzymes and structure, carbohydrates are sugar-based and provide quick energy plus some structural roles, and nucleic acids store genetic information. Therefore triglycerides belong to lipids.
