In the specialized field of biochemical research, few molecules have garnered as much interest as the Met enkephalin peptide. As someone who has spent significant [D-Ala2]-Met-Enkephalin time sourcing and analyz Met-Enkephalin Peptide ing various compounds for laboratory study, I have found that understanding the nuances of this specific sequence is essential for any serious researcher.
Defining the Molecule: What is Met Enkephalin?
At its core, Met-enkephalin (often referred to as [Met5]-Enkephalin) is a naturally occurring, endogenous opioid peptide. Structurally, it is defined as a pentapeptide with the sequence H-Tyr-Gly-Gly-Phe-Met-OH. It is critical to distinguish this from its counterpart, Leu-enkephalin, as the two represent the primary forms of these signaling molecules.
Scientific literature frequently notes that Enkephalins are endogenous pentapeptides involved in regulating pain sensation (nociception). Beyond its role in the central nervous system, it is fascinating to note that Met-enkephalin also functions as a growth factor on many cell types at receptors that are distinct from standard neuronal opioid receptors.
Technical Specifications for Laboratory Use
When identifying high-quality compounds, researchers should Description.

For instance, the Molecular Weight: 701.33 (often c Methionine enkephalin is a small opiate peptideproduced by both peripheral tissues and the CNS that has neuroimmune functions. It is transported from the CNS Read more ited for derivatives) or the standard weight of approximately 573.67 Da for the base peptide, is a key marker of purity.
During my search for reliable reagents, I noticed that Product Name: Met-Enkephalin, Peptide is often listed with a purity requirement of ≥95% or ≥96% via HPLC. Whether you are looking at a catalog item like NOV-PE-55181-1mg — 1 mg priced at $424.00, or a smaller quantity around $252.00, the consistency of the lyophilized powder is paramount. Proper storage—avoiding repeated freeze-thaw cycles—is mandatory to maintain the integrity of the peptide.
Physiological Insights and Research Applications
The diversity of this molecule’s function is vast. Research has explored how ME modulates thalamic-driven excitatory and inhibitory synaptic transmission in neuronal cultures. Furthermore, it serves as an Opioid agonist that inhibits vas deferens contractions mediated through delta receptors.
Interestingly, the study of these molecules extends beyond traditional models. Researchers have even investigated Met-enkephalin in chicke [Arg0]-Met-Enkephalin ns and other animal models to understand stress responses. As an endogenous opioid and beta-endorphin relative, it has been discussed in contexts ranging from neuroimmunology to its potential as an endogenous pentapeptide with morphine-like activity.
Comparisons and Structural Nuances
When differentiating between types, one might ask: what is the difference between this and other heptapeptides? For example, Met-Enkephalin-Arg-Phe is a naturally occurring heptapeptide with analgesic activity, which differs from the standard pentapeptide.
Methionine is the defining amino acid at the C-terminus of this molecule. While MET-enkephalin (MENK) is an endogenous opioid peptide, it is often compared to its leucine-containing relative. Both are vital, but their specific binding affinities to $\mu$- and $\delta$-opioid receptors are what draw investigators to utilize them in controlled, in vitro settings.
Final Thoughts on Sourcing
Whether you are investigating why Methionine enkephalin is a small opiate peptide produced by peripheral tissues or studying its role in cell growth, always ensure you are acquiring your materials from reputable suppliers who provide a Certificate of Analysis. The study of this endogenous opioid peptide remains a cornerstone of neurobiological research, and its potential for future discovery in laboratory settings is immense.
