The peptides in the human body will function in many ways. The peptides will regulate the metabolism and also mediate the pain signals in your body. The large size and specific area of the peptides will allow them for more specific docking to the target molecules. Peptides are considered as the desirable candidates for therapeutics in the recent days. The peptides may also contain up to fifty amino acid residues. The proteins are the molecules which have more than fifty amino acid residues. The peptides can act as a growth factor because they play a vital role in endocrine signalling. The peptides are produced by other organisms as a purpose of defence like the fungal production of cyclosporin. Without the application of peptides, we cannot imagine the modern medicinal and biochemical research.
Amino acids residue:
The structure and activities of the peptides are considered as an important aspect of the strategies for the synthesis of peptides. The molecules are present in the residue of amino acids. The polymer molecules which have ten or less than ten amino acid residues are termed to be called as oligopeptides. Peptides play a crucial role in the cell signalling. The function of peptides can be used for the therapeutic treatments and research. The peptides and proteins will come under the category of polypeptide chains. The polypeptide chains will have two or more amino acids which are coupled by a peptide bond. The peptide is a special linkage between nitrogen atom of one amino acid and the carboxyl carbon atom of another amino acid. Depending on the amount of amino acid, the peptides will differ from the proteins.
The activity of the peptides can be increased by the incorporating modifications. Compared to the protein counterparts, the therapeutic peptide has some advantages. The purification and structural analysis are expensive and complex. The biologics are almost invariable and must be injected. The peptides will reduce the risk of side effects but it will depend on the type of peptides you select. The proteases can rapidly metabolize the peptides and also allows the short time activity in the body. The proteins are also called as the biological therapeutics which has an increasing share in the pharmaceutical marketplace from the past few years. The biologics are often highly effective and safe and they are produced in bioreactors by using the whole cells.
