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: -The name amino acid comes from the presence of an amino group and an acid carboxyl group (-COOH) in these molecules. Amino acids are the monomers which make up proteins. Amino acids are the monomer units.
Detailed explanation-4: -Explanation: Amino acids are the building blocks (or monomers) of a polypeptide chain. The polypeptide chain then gets folded up into a 3D for that is called a protein. Amino acids bond together through an amide condensation reaction to form an Amide bond. This is called a peptide bond in biology.
Detailed explanation-5: -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. Each type of protein has a unique sequence of amino acids, exactly the same from one molecule to the next.
