Verified step by step guidance1
Understand the question: The problem is asking which category of nutrients is made up of amino acids. Amino acids are the building blocks of a specific type of macromolecule.
Recall the structure and function of amino acids: Amino acids are organic compounds that contain both an amino group (-NH₂) and a carboxyl group (-COOH). They are linked together by peptide bonds to form chains.
Identify the macromolecule formed by amino acids: When amino acids are joined together, they form polypeptides, which fold into functional structures known as proteins.
Compare the options provided: Proteins are made of amino acids, while lipids, vitamins, and carbohydrates are composed of different types of molecules. For example, lipids are made of fatty acids and glycerol, carbohydrates are made of monosaccharides, and vitamins are small organic compounds with diverse structures.
Conclude that the correct answer is 'Proteins,' as they are the only category of nutrients comprised of amino acids.
