Detailed explanation-1: -The exact amino acid sequence of each protein drives it to fold into its own unique and biologically active three-dimensional fold also known as the tertiary structure.
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.
Detailed explanation-5: -Tertiary (3˚) Structure There is therefore a great diversity of possible protein sequences. The linear chains fold into specific three-dimensional conformations, which are determined by the sequence of amino acids and therefore are also extremely diverse, ranging from completely fibrous to globular.
