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 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-3: -Explanation: Amino acids are the building blocks of proteins, and have an amine group (−NH2), as well as a carboxyl group (−COOH) . When hundreds and thousands of them combine using peptide bonds, they form proteins, which are nutrients essential for survival. So, we can say that amino acids are monomers of proteins.

Detailed explanation-4: -Of these 20 amino acids, nine amino acids are essential: Phenylalanine. Valine.

Detailed explanation-5: -Building Blocks or Elementary Units: Proteins Monomers The order of amino acids in which they are arranged is called the primary structure of a protein. Chemically speaking, an amino acid molecule consists of three groups, i.e., amino group (-NH2), carboxylic acid group (-COOH), and side-chain (R group).
