Peptides are known as smaller versions of proteins. There are many cosmetic, as well as health, products that contain different proteins. They have different uses such as their potential anti-aging, anti-inflammatory, or muscle building properties. Research has shown that some types could have a beneficial role in slowing down the aging process. They are known to reduce inflammation and also destroy microbes. Both peptides and proteins contain amino acids, although peptides contain far fewer amino acids than proteins. Like proteins, they are naturally present in foods.
What are peptides
Peptides are naturally occurring biological molecules. They are found in all living organisms and play a key role in all manner of biological activity. Like proteins, are formed (synthesized) naturally from transcription of a sequence of the genetic code, DNA. Transcription is the biological process of copying a specific DNA gene sequence into a messenger molecule, mRNA, which then carries the code for a given peptide or protein. Reading from the MRNA, a chain of amino acids is joined together by peptide bonds to form a single molecule.
In order for a peptide to exert its effects, it must bind to a receptor specific for that peptide and which is located in the membrane of relevant cells. A receptor penetrates the cell membrane and consists of an extracellular domain where the peptide binds, and an intracellular domain through which the peptide exerts its function upon binding and activation of the receptor. An example is the GLP-1 receptor, which is located on beta cells in the pancreas. Upon activation of the receptor by natural GLP-1 or a peptide analog (a synthesized molecule mimicking the effect of natural GLP-1, such as our lixisenatide), the cell is stimulated through a series of biological events to release insulin.
