When exploring the fascinating world of endogenous peptides, the alpha msh peptide sequence often stands out due to its unique structural complexity and biological significance. Known formally as alpha-melanocyte-stimulating hormone ($\alpha$-MSH or melanotropin), this tridecapeptide α-Melanocyte-stimulating hormone - Wikipedia serves as a foundational subject for those interested in the biochemical properties of the melanocortin family.
The Structural Identity of $\alpha$-MSH
At its core, the a-MSH peptide is an endogenous peptide hormone defined by a precise 2天前—At its core, thea-MSH peptideis an endogenous peptide hormone with a tridecapeptide structure, meaning it is composed of 13 amino acids. This arrangement of amino acids. As a 13-amino acid peptide, it is derived from the proteolytic cleavage of the larger proopiomelano Sequence ·Ac-Ser-Tyr-Ser-Met-Glu-His-Phe-Arg-Trp-Gly-Lys-Pro-Val-NH2; Synonym · alpha-Melanocyte Stimulating Hormone; Ac-ACTH (1-13) amide ; CAS Number · [581-05-5] cortin (POMC) precursor. The amino-acid sequence of the alpha-melanocyte-stimulating hormone is widely recognized and documented in scientific literature.
The full peptide sequence is represented as:
Ac-Ser-Tyr-Ser-Met-Glu-His-Phe-Arg-Trp-Gly-Lys-Pro-Val-NH2
This sequence is often abbreviated as SYSMEHFRWGKPV. In its synthetic form, researchers often observe specific modifications:
* N-terminal: Acetylation (Ac) at the Serine-1 position.
* C-terminal: Amidation (-NH2) at the Valine-13 position.
* Molecular Formula: $C_{77}H_{109}N_{21}O_{19}S$.
* Molecular Weight: Approximately 1664.9 Da.
Analyzing the Sequence Components
The architecture of this alpha-melanocyte-stimulating hormone ensures its functional specificity. The sequence is highly conserved, and the Arg8-Trp9 segment has been identified as a fundamental component of the minimal message sequences necessary for activity. Whether researchers are studying a-MSH, amide or other variants, these sequences remain central to understanding how the peptide interacts with melanocortin (MC) receptors.
In my own review of the human: Ac-Ser-Tyr-Ser-Met-Glu-His-Phe-Arg-Trp-Gly-Lys-Pro-Val-NH2 configuration, the precision of the SYSMEHFRWGKPV chain is striking. It is categorized as a tridecapeptide, meaning it is composed of exactly 13 amino acids.

Research Context and Observations
The alpha-melanocyte-stimulating hormone ($\alpha$-MSH, or melanotropin) is frequently utilized in laboratory se An Emerging Anti-Inflammatory Antimicrobial Peptide - PMC - NIH ttings to investigate cellular pathways. Because it is a tridecapeptide, it requires careful handling and storage protocols to maintain its structural integrity.
For those researching the alpha melanocyte-stimulating hormone (alpha-MSH), it is helpful to distinguish between endogenous production—which occurs in the anterior pituitary gland—and synthetic versions used for analytical chemistry. The alpha component refers to its specific position within the melanocortin family, while the MSH acronym denotes its historical association with pigmentary cellular responses.
Final Thoughts on Peptide Integrity
Whether you are reviewing technical data for $\alpha$-MSH or analyzing the a-MSH is a tridecapeptide classification, the consistency of the Ac-Ser-Tyr-Ser-Met-Glu-His N-terminal starting point is a key marker for authenticity in synthetic samples. Understanding the peptide structure is the first step in any rigorous investigation into the properties of this ancient, neuroimmunomodulatory molecule.
