amount of data. As the hardware technology advancing, the cost of storing is decreasing. The biological data is available in different formats and is comparatively more complex. Knowledge discovery from these large and complex databases is the key problem of this era. Data mining and machine learning techniques are needed which can scale to the size of the problems and can be customized to the application of biology. In the present research work, the Chou-Fasman Method is implemented with the help of data mining. Protein structure determination and prediction has been a focal research subject in the field of bioinformatics due to the importance of protein structure in understanding the biological and chemical activities of organisms. The experimental methods used by biotechnologists to determine the structures of proteins demand sophisticated equipment and time. A host of computational methods are developed to predict the location of secondary structure elements in proteins for complementing or creating insights into experimental results. Cluster analysis is used as data mining model to retrieve the results. I. INTRODUCTION ROTEINS are complex organic compounds that consist of amino acids joined by peptide bonds. Proteins are essential to the structure and function of all living cells and viruses. Many proteins function as enzymes or form subunits of enzymes. Some proteins play structural or mechanical roles. Some proteins function in immune response and the storage and transport of various ligands. Proteins serve as nutrients as well; they provide the organism with the amino acids that are not synthesized by that organism. Proteins are amongst the most actively studied molecules in biochemistry. An amino acid is any molecule that contains both an amino group and a carboxylic acid group. An amino acid residue is the residuals of an amino acid after it forms a peptide bond and loses a water molecule.
