Detailed explanation-1: -Proteins are made up of hundreds or thousands of smaller units called amino acids, which are attached to one another in long chains. There are 20 different types of amino acids that can be combined to make a protein.

Detailed explanation-2: -Although more than 100 amino acids occur in nature, particularly in plants, only 20 types are commonly found in most proteins. In protein molecules the -amino acids are linked to each other by peptide bonds between the amino group of one amino acid and the carboxyl group of its neighbour.

Detailed explanation-3: -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.

Detailed explanation-4: -The proteins with the smaller units of molecules or monomers called amino acids. Amino acids are organic molecules, which have two ends named amino and carboxyl terminal ends. There are 21 amino acids, which are called monomers.

Detailed explanation-5: -Proteins are built from a set of only twenty amino acids, each of which has a unique side chain. The side chains of amino acids have different chemistries. The largest group of amino acids have nonpolar side chains.
