Monomer of protein

Answer 1

The monomer of a protein is an amino acid. Amino acids are organic compounds that serve as the building blocks of proteins. Each amino acid has a central carbon atom, an amino group (–NH2), a carboxyl group (–COOH), a hydrogen atom, and a variable side chain (R group) that distinguishes one amino acid from another. There are 20 standard amino acids that combine in various sequences to form the diverse range of proteins necessary for biological functions.
