Explanation:
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: -Every amino acid also has another atom or group of atoms bonded to the central atom known as the R group (Figure 1). The name “amino acid” is derived from the fact that they contain both amino group and carboxyl-acid-group in their basic structure. As mentioned, there are 20 amino acids present in proteins.
