Verified step by step guidance

Understand the structure and function of fatty acids: Fatty acids are long hydrocarbon chains with a carboxyl group (-COOH) at one end. They are hydrophobic and serve as building blocks for certain biomolecules.

Review the definition of lipids: Lipids are a class of biomolecules that are primarily composed of fatty acids and glycerol. They include triglycerides, phospholipids, and sterols, and are essential for energy storage, membrane structure, and signaling.

Compare lipids with other biomolecules: Carbohydrates are composed of monosaccharides (sugars), nucleic acids are made of nucleotides, and proteins are composed of amino acids. None of these are primarily composed of fatty acids.

Identify the correct answer: Since lipids are the biomolecules primarily composed of fatty acids, they are the correct answer to the question.

Conclude with clarification: Fatty acids are integral to lipids, but not to carbohydrates, nucleic acids, or proteins, which are composed of entirely different building blocks.
