Lipids are naturally occurring substances which are chemically:
Correct answer: D. Esters
- A. Proteins
- B. Amino acids
- C. Carbohydrates
- D. Esters
Explanation
Lipids are predominantly made up of fatty acids and glycerol. The ester bond formed between these components categorizes lipids as esters. This chemical structure is essential for their role in energy storage, insulation, and cell membrane formation. The other options, such as proteins, amino acids, and carbohydrates, represent different classes of biomolecules with distinct structures and functions. Proteins are polymers of amino acids, carbohydrates are simple sugars or complex polymers like starch, and amino acids are the monomers that constitute proteins.

About Lipids
Lipids include fats, oils, waxes, phospholipids and steroids, which are largely insoluble in water and soluble in organic solvents. Coverage includes glycerol and fatty acids, ester bond formation, saturated and unsaturated fats, triglyceride functions, and phospholipids in cell membranes.
