In the specialized field of peptide research, few molecules possess the structural complexity and functional versatility of the galanin peptide. As someone who has spent considerable time studying the biochemical landscape of neuropeptides, I have found the study of this specific cha prepro-Galanin (65-88) (Human) in to be a fascinating endeavor. Whether one is examining the human variant or the broader family of related compounds, understanding the underlying mechanisms of these molecules is essential for any serious researcher.
Molecular Structure and Characteristics
To understand the galanin peptide, one must first look at its fundamental architecture. In humans, human galanin (GAL, P22466) is a 30 amino-acid non-amidated peptide, setting it apart from its counterparts in other mammals where it typically exists as a 29 amino acid long peptide with C-terminal amidation.
The name itself is derived from the N-terminal glycine and the C-terminal alanine, which define its structural identity. As a 29–30 amino acid molecule, it functions as a critical signaling agent. Beyond the primary peptide, research often intersects with the Galanin Message Associated Peptide (GMAP), which is par Galanin-Like Peptide (human) is a 60 amino acid neuropeptide. Galanin-Like Peptide (human) plays an important role in the regulation of feeding, t o Physiology, Signaling, and Pharmacology of Galanin Peptides f the pre-progalanin molecule—a precursor that warrants attention when discussing synthesis and biological availability.
Physiological Distribution and Signaling
Galanin is a neuropeptide widely expressed in the gut, brain, and spinal cord of mammals, making it a ubiquitous player in the central and peripheral nervous systems. Because galanin is a peptide that acts as an endocrine hormone of the central and peripheral nervous systems, it does not act in isolation. Instead, it binds to a specific receptor family that currently comprises 3 members: GalR1, GalR2, and GalR3. These are all G-protein-coupled receptors, which facilitate the diverse signaling pathways associated with the molecule.
In my experience reviewing various laboratory reports, the specificity of these receptors is key. For instance, Galanin (1-30) (human) is frequently cited for its role as a potent agonist. Furthermore, the galani Galanin-Like Peptide (human) | Cas# 245114-99-2 n peptide family is undoubtedly involved in the regulation of inflammatory processes, and it is often noted that galanin can be regarded as an immunomodulatory peptide capable of influencing systemic responses.
Functional Diversity
The functional reach of this molecule is extensive. Researchers have observed that galanin regulates whole-brain activity and can even impact smooth muscle tissue, as it contracts smooth muscle of the gastrointestinal and genitourinary tract.
When looking at the broader picture, we must also consider the Galanin-like peptide (GALP). This 60 amino acid neuropeptide is distinct from the primary galanin chain but shares significant interest within the scientific community. The study of these compounds is not merely theoretical; galanin has been extensively studied in a number of physiologic systems, ranging from metabolic regulation to the modulation of insulin release.

For those interested in exploring these compounds, it is important to distinguish between the various forms available for study. Specialized variants like the Galanin (2-11) peptide are often utilized in specific assays to isolate receptor interactions.
When sourcing these materials, one might encounter varying price points—such as the $938.00 benchmarks for high-purity human-grade material—reflecting the complexity of synthesizing these 30-amino acid chains. Whether exploring the standard peptide or the 60-amino acid Galanin-like peptide (GALP), the focus remains on the high-level signaling interactions that define this field.
Conclusion
Galanin is a neurohormone as well as a neurotransmitter, and its role as a neuropeptide present in humans and other mammals remains a cornerstone of modern biochemical investigation.
