Detailed explanation-1: -The Primary structure of proteins is the exact ordering of amino acids forming their chains. The exact sequence of the proteins is very important as it determines the final fold and therefore the function of the protein.

Detailed explanation-2: -The Significance of Protein Structure Their tertiary structure gives proteins a very specific shape and is an important feature in the ‘lock and key’ function of enzymes, or receptor sites on cell membranes.

Detailed explanation-3: -Levels of Structure The significance of the unique sequence, or order, of amino acids, known as the protein’s primary structure, is that it dictates the 3-D conformation the folded protein will have. This conformation, in turn, will determine the function of the protein.

Detailed explanation-4: -The interactions and bonds of side chains within a particular protein determine its tertiary structure. The protein tertiary structure is defined by its atomic coordinates. These coordinates may refer either to a protein domain or to the entire tertiary structure.
