What classification of molecules includes fats, oils, waxes, and cholesterol?

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

Answer: (D)

The classification of molecules that includes fats, oils, waxes, and cholesterol is referred to as lipids. Lipids are a diverse group of hydrophobic organic compounds that are insoluble in water but soluble in nonpolar solvents. They play crucial roles in biological systems, including energy storage, structural components of cell membranes (such as phospholipids), and as signaling molecules (like steroid hormones). Each of the mentioned substances, such as fats and oils, serve as energy reserves, while waxes can provide protective coatings on plants and animals. Cholesterol, a type of steroid, is vital for maintaining membrane fluidity and serves as a precursor for synthesizing other important steroids. Therefore, the correct answer accurately encompasses these various types of molecular structures and their functions within biological organisms.
