In human organism amino acids are connected and glued by help of polymers named peptides. This connection is named peptide bond. Protein is the molecule that is formed by lots of peptides and it is also called polypeptide molecule. The main thing which draws interest of the scientists analyzing peptides is the type and quantity of amino acid. Maybe it is logical to name the products of peptide synthesis from amino acid as proteins but they are usually called peptides. Actually it is not so significant how to call the processes or substances, because modern technologies affect improving of all areas of science and provide better opportunities everyday. Peptides are classified on the basis of how they are produced. First class of peptides named ribosomal. They are formed as a result of translation of messenger ribonucleic acid. To reach maturity they are frequently subjected to digestion by ferments. Scientists name such process as proteolysis. In higher creatures ribosomal peptides may operate as hormones or even signaling matters. The next type of peptides includes peptides that are created not by ribosome, but by putting together by some unique ferment features. Glutathione is one of the most noted specimens of that class. Some organisms use them as antioxidant matter. Discoveries say that peptides are included even in some plants. The other class of peptides is comprised into many sorts of milk and digest meat. When bacteria or fungi are grown in a dish, peptones are used to nurture them. Peptides significantly simplify the progress of molecular biological researches because excluding the need to have a pure protein as precisely peptides influence development of peptide antibodies. Antigenic peptides can be synthesized for only a part of the necessary protein. Some antibodies in the animals are produced exactly by means of these parts. Mass spectrometry utilizes peptides to perform a great deal of various discoveries that is why interest to peptides raises significantly. Mass spectrometry can monitor all the way of peptide producing and development and all the needed information is just mass and sequence of peptide. Peptides also assist scientists analyze and uncover new and existing proteins and their functions. Biologists create peptides, perform experiments where interactions between peptides and proteins occur and utilize these empirical findings to improve our understanding of different illnesses. Maybe, even such serious illnesses as cancer will be cured by the methods based on peptides analysis.
