Question

what is the monomer of proteins? amino acids polypeptides nucleotide polysaccharide

Explanation:

Proteins are macromolecules made by linking amino acids through peptide bonds. A monomer is a single unit that makes up a polymer. Amino acids are the individual units (monomers) that polymerize to form proteins (polymers like polypeptides, which are chains of amino acids). Polypeptides are polymers of amino acids (not monomers), nucleotides are monomers of nucleic acids, and polysaccharides are polymers of sugars (monomers like monosaccharides). So the monomer of proteins is amino acids.

Answer:

A. Amino Acids
