Detailed explanation-1: -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-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: -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-4: -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.
