Amino acids are monomers for which class of biochemicals?

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

Answer: (B)

Verified step by step guidance

1. Understand the question: Amino acids are the building blocks (monomers) for a specific class of biochemicals. The goal is to identify which class they belong to.
2. Recall the definition of amino acids: Amino acids are organic molecules that contain both an amino group (-NH₂) and a carboxyl group (-COOH), along with a unique side chain (R group). They are essential for forming larger macromolecules.
3. Review the classes of biochemicals provided in the options: Lipids, Proteins, Polysaccharides, and Nucleic acids. Each class has distinct monomers and functions. For example, lipids are composed of fatty acids and glycerol, polysaccharides are made of monosaccharides, and nucleic acids are composed of nucleotides.
4. Connect amino acids to proteins: Proteins are polymers made up of amino acids linked together by peptide bonds. This process forms polypeptide chains, which fold into functional proteins.
5. Conclude that amino acids are monomers specifically for proteins, as they do not serve as building blocks for lipids, polysaccharides, or nucleic acids.
