There are a lot of methods to research the structure of protein, but the most precise is x-ray analysis. Protein crystallography is considered to be just a section of x-ray crystallography but it is truly important. Protein crystallography is a perfect system of learning more about the secondary, and as it found out triple structure of protein. Usually, on the basis of x-ray crystallography data it is possible do determine the protein quaternary structure, but it is not always available. Many different circumstances can influence the defining of protein texture. Folding of protein is the main structural property of protein molecule. The protein is quite wonderful matter, because all the information about it is collected and folded in its primary structure. So many scientists worldwide try to determine the protein function more properly. When the ground of protein is completely researched, there will be a chance to define many different characteristics of protein as classification of protein, protein role etc. and just learn more about function of protein. There are many protein problems which are not solved regardless of the current progress. There is some definite relations between the structure of protein and its basic texture, but they can not be described. Scientists managed to work out that problems only for the class of proteins called peptides. The description of peptides is the demesne that is well-studied. Owing to the modern technologies we have a chance to execute the peptide synthesis process.
