Detailed explanation-1: -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-2: -Amino acids are the monomers that make up proteins. Each amino acid has the same fundamental structure, which consists of a central carbon atom, also known as the alpha () carbon, bonded to an amino group (NH2), a carboxyl group (COOH), and to a hydrogen atom.
Detailed explanation-3: -Proteins are the most abundant biomolecules of the living system. A protein is made up of amino acids. Thus, amino acid behaves as a monomer in the formation of a polymer that is a protein (The polymer is itself protein).
Detailed explanation-4: -Amino acids are linked together into linear chains called polypeptides. While the terms polypeptide and protein are sometimes used interchangeably, a polypeptide is technically a polymer of amino acids, whereas the term protein is a polypeptide or polypeptides that have a distinct shape and a unique function.
