Question

amino acids are the monomers of

carbohydrates
lipids
proteins
nucleic acids

Explanation:

Amino acids are the building blocks (monomers) of proteins. Proteins are polymers formed by the condensation reaction of amino acids, where a peptide bond is formed between the amino group of one amino acid and the carboxyl group of another, releasing a water molecule. Nucleic acids are made of nucleotides, lipids are a diverse group (not all have a single monomer like fatty acids and glycerol for some lipids), and carbohydrates are made of monosaccharides.

Answer:

proteins
