In the evolving field of biochemistry and peptide research, few molecules draw as much fascination as vasoactive intestinal polypeptide. Often abbreviated as VIP, this compound represents a 28-amino-acid multifunctional peptide that has become a 010397: Vasoactive Intestinal Polypeptide (VIP), Plasma primary subject of study for those interested in the intricate signaling mechanisms of the body. My by SI Said·1988·Cited by 11—Thevasoactive intestinal peptide (VIP) was so named because of its isolation from the intestinal extracts and the potent vasodilator activity that guided Read more personal journey into exploring such compounds began with a desire to understand how these neuroendocrine messengers function at a molecular level.
What is Vasoactive Intestinal Polypeptide?
At its core, vasoactive intestinal polypeptide (VIP) is a peptide hormone that is vasoactive in the intestine. It is a hormone found in the pancreas, intestine, and central nervous system, acting as a critical bridge between various bodily tissues. Researchers often focus on its role as a neurotransmitter, as it is a neuroendocrine pep Vasoactive Intestinal Peptide (10-28) [69856-17-3]. SHIP COLD. Catalog Number: P002612. Sequence: Tyr-Thr-Arg-Leu Read more tide distributed throughout the human body, including the CNS.
From a structural perspective, the molecule is a 28-amino-acid multifunctional peptide. This specific sequence is what confers its unique ability to interact with receptors, such as the VPAC1 receptor, influencing everything from electrolyte secretion to smooth muscle tone.
The Role of VIP in Biological Systems
When researching this peptide, one quickly learns that VIP is a peptide hormone with profound effects on physiology. Here are some of the key functional characteristics observed in laboratory settings:
* Smooth Muscle Relaxation: One of the most verifiable properties of this peptide is that VIP induces smooth muscle relaxation, which contributes to its status as a potent vasodilator.
* Gastrointestinal Modulation: Because it is a gastrointestinal peptide hormone consisting of 28 amino acids, it plays a massive role in regulating the digestive tract. It stimulates the secretion of water and electrolytes into the intestinal lumen.
* Neurological Signaling: As a neurotransmitter, it helps modulate signaling pathways, which is why it is frequently discussed in neuroscience literature.
Insights from Research and Laboratory Analysis
For those interested in the scientific literature, the vasoactive intestinal polypeptide (VIP) is often studied alongside its fragments, such as Vasoactive Intestinal Peptide (10-28). These truncated versions are frequently used in research to isolate specific receptor-binding activities without the full scope of the native molecule’s systemic effects.
In a clinical or diagnostic context, professionals often utilize a test that measures the amount of VIP in the blood. This is important for detecting vasoactive intestinal polypeptide-producing tumors, which are typically identified in the pancreas. Understanding these markers is essential for anyone tracking the biological footprint of this molecule.
