Peptones are extracted from animal milk or meat digested by proteolysis. In addition to containing small peptides, the resulting spray-dried material [clarification needed] includes fats, metals, salts, vitamins and many other biological compounds. Peptones are applied on nutrient media for growing bacteria and fungi.
Peptide fragments refer to fragments of proteins that are applied to identify or quantify the source protein. Usually these are the products of enzymatic degradation performed in the laboratory on a controlled sample, but can also be forensic or paleontological samples that have been degraded by natural effects.
Applications in Sports
The term peptide has been applied to mean secretagogue peptides and peptide hormones in sports doping matters: secretagogue peptides are distinguished as Schedule 2 (S2) stricted substances on the World Anti-Doping Agency (WADA) Prohibited List, and are therefore stricted for use by professional athletes both in and out of competition.
Such secretagogue peptides have been on the WADA prohibited substances list since at least 2008. The Australian Crime Commission cited the alleged misuse of secretagogue peptides in Australian sport including growth hormone releasing peptides CJC-1295, GHRP-6, and GHSR (gene) hexarelin.
There is ongoing argument on the legality of utilizing secretagogue peptides in sports.
What are Peptides?
Peptides are biologically appearing short chains of amino acid monomers bridged by peptide (amide) bonds.
The covalent chemical bonds are constructed when the carboxyl family of one amino acid performs with the amine family of another.
The shortest peptides are dipeptides, inculding 2 amino acids joined by a single peptide bond, followed by tripeptides, tetrapeptides, etc. Polypeptides are long, consistent, and unbranched peptide chains.
Thus, peptides fall under the broad chemical series of biological oligomers and polymers, along with nucleic acids, oligosaccharides and polysaccharides, etc.
Peptides are diffrentiated from proteins on the basis of size, and as an arbitrary benchmark can be understood to have approximately 50 or fewer amino acids.
Proteins consist of one or more polypeptides organized in a biologically functional way, often bound to ligands such as coenzymes and cofactors, or to another protein or other macromolecule (DNA, RNA, etc.), or to complicated macromolecular assemblies.
Finally, while aspects of the lab techniques utilized to peptides versus polypeptides and proteins divers (e.g., the specifics of electrophoresis, chromatography, etc.), the size boundaries that distinguish peptides from polypeptides and proteins are not absolute:
long peptides such as amyloid beta have been referred to as proteins, and smaller proteins like insulin have been regarded as peptides.
Amino acids that have been incorporated into peptides are called "residues" due to the release of either a hydrogen ion from the amine end or a hydroxyl ion from the carboxyl end, or both, as a water molecule is released during formation of each amide bond.
All peptides except cyclic peptides have an N-terminal and C-terminal impurity at the end of the peptide (as shown for the tetrapeptide in the image).
