In the world of peptide research, understanding the fundamental properties of specific sequences is crucial for any enthusiast or laboratory professional. One of the most frequently discussed molecules in neurobiological studies is Neuropeptide Y. As someone who has spent considerable time exploring the structural nuances of various peptides, I have found that the specific physical characteristics of this molecule are what make it truly fascinating for analytical comparison.
Defining Neuropeptide Y Size and Composition
When we look at the core data, Neuropeptide Y is consistently identified as a 36-amino acid neuropeptide. This spec Neuropeptide Y - an overview ific length is a hallmark of the pancreatic polypeptide family, which also includes peptide YY and pancreatic polypeptides. From a technical standpoint, the Molecular Weight: 4271.68 daltons is a critical parameter for Structural basis of neuropeptide Y signaling through Y1 - PMC those verifying the purity and identity of synthetic batches Neuropeptide Y - an overview | ScienceDirect Topics .
For those sourcing these compounds by D Jacques · 1997 · Cited by 66 — The aim of the present study was to investigate the existence and distribution of neuropeptide Y receptor subtypes in various regions of the normal human brain for research, you will often find them listed in standardized formats. For instance, a common 1 mg vial is the standard quantity for many experimental protocols. Whether you are investigating the NPY signaling pathways or structural analogs, having a clear understanding that Neuropeptide Y is a 36-amino-acid endogenous neuropeptide serves as the baseline for all subsequent research.
Why Structural Precision Matters
The structural integrity of the peptide is paramount. Research indicates that the amidated C-terminus is essential for its biological activity and receptor binding. In my own review of different suppliers, I have noted that high-quality synthetic neuropeptide Y must strictly adhere to this 36-amino acid sequence to maintain its functional conformation.
When discussing neuropeptide Y, it is helpful to categorize its properties into three distinct areas:
1. Sequence Integrity: The by S Shen · 2024 · Cited by 7 — Neuropeptide Y (NPY), a 36‐amino‐acid peptide, functions as a neurotransmitter in both the central and peripheral nervous systems by activating the NPY receptor 36-amino acid chain must be preserved to ensure it matches the endogenous human sequence.
2. Molecular Weight: At 4271.68, the mass spectrometry verification should align closely with this figure to ensure no truncation has occurred during synthesis.
3. Purity Standards: Always look for certificates of analysis (COA) that verify the peptide content relative to the total weight of the sample, particularly when dealing with 1 mg aliquots.
Comparative Observations
In the broader context of peptide research, comparing this molecule to other family members reveals why its length is so significant. It shares a common fold with o Neuropeptide Y human ; Molecular Weight: 4271.68 ; UNSPSC Code: 12352200 ; NACRES: NA.32 ; biological source. synthetic ; Quality Segment. 200 ther members of its family, yet its unique amino acid distribution provides the specific selectivity required for its various receptors.
Neuropeptide Y(29-64) | PeptideDuring my research, I have encountered various discussions regarding NPY and its role in homeostatic processes. While the literature is vast, focusing on the basics—such as the fact that Neuropeptide Y is a 36-amino-acid endogenous neuropeptide—provides a stable foundation for understanding how researchers evaluate its efficacy in different biological models.
Final Thoughts for Enthusiasts
For those interested in the structural analysis of peptides, the neuropeptide Y molecule remains a primary subject of interest due to its evolutionary conservation. Whether you are analyzing its molecular weight or exploring its complex receptor interactions, always ensure your information is derived from peer-reviewed databases and reputable chemical suppliers.
By maintaining a focus on the structural parameters—specifically its 36-amino acid neuropeptide configuration—you can better appreciate the precision required in modern peptide science. Always prioritize quality and documentation when adding such compounds to your research collection, and ensure that your handling procedures account for the delicate nature of these 36-amino acid sequences.
