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: -For example, proteins are composed of monomers called amino acids.

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: -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-5: -Recall from Chapter 2 that there are 20 types of amino acids in proteins, each with different chemical properties. A protein molecule is made from a long chain of these amino acids, each linked to its neighbor through a covalent peptide bond (Figure 3-1). Proteins are therefore also known as polypeptides.
