Newly scientists have contrived the alternative system to learn the structure of protein, that is x-ray dissection. Really, the protein crystallography is not detached part, but it is very important segment of x-ray crystallography. Protein crystallography does allow defining protein secondary structure and subsequently threefold structure of protein. On the basis of protein crystallography the quaternary structure of protein can be described. In certain cases protein shows its different properties, it depends on some factors. Folding of protein is the main structural feature of protein molecule. The protein is quite wonderful substance, because all the information about it is saved and folded in its basic texture. So many scientists from all over the world attempt to find the protein more properly. A lot of very important characteristics of protein as protein classification, its role are still can't be learned due to lack of knowledge about it, so we have to learn more about classification of protein. Even having got a modern technologies and superb devices the basic problem is not solved. There is some definite connections between the texture of protein and its primary texture, but they can not be specified. Peptide is the independent type of the proteins that for that problem has been already solved. The function of peptides is a well-studied domain. Thanks to the modern technologies we have a chance to execute the peptide synthesis process.
