Detailed explanation-1: -Amino acids are the monomers that make up proteins.
Detailed explanation-2: -For example, proteins are composed of monomers called amino acids. They are linked together to form a polypeptide chain, which folds into a three dimensional (3D) structure to constitute a functional protein (Figure 1).
Detailed explanation-3: -Amino acids do not have single monomers. They are basic compounds bound to the same molecule, with an amino group and a group of carboxylic acids. Instead, amino acids are monomers of proteins, long chains of amino acids that are bound together by amide bonds.
Detailed explanation-4: -Proteins are polymers; the monomers which make them up are amino acids. Proteins may be used as enzymes, structural molecules, energy storage molecules, transport molecules, hormones, and many other metabolic uses. They may have up to four levels of structure.
