Peptide YYfoods Peptide YY (PYY) is a crucial gut hormone that plays a significant role in regulating appetite and digestion. Its full name, pancreatic peptide YY, hints at its origins and function, though it is primarily secreted by L-cells in the lining of the small and large intestines in response to food intake. This peptide acts as an anorectic hormone, signaling satiety to the brain and helping to reduce food consumptionPeptide YY(1-36) and Peptide YY(3-36): Part I..... Understanding Peptide YY (PYY) involves exploring its structure, release, mechanisms of action, and its implications for metabolic health.
Peptide YY is a 36-amino acid peptide belonging to the pancreatic polypeptide family, which also includes neuropeptide Y (NPY) and pancreatic polypeptide (PP). The PYY gene encodes this hormone. While its name suggests a connection to the pancreas, the primary production site for PYY is within the enteroendocrine L-cells found in the distal small intestine and colon. These cells release PYY into the bloodstream after the ingestion of nutrients, particularly fats and proteins.Thisgutpeptide inhibits exocrine pancreatic secretion, has a vasoconstrictory action and inhibitis jejunal and colonic mobility.
The primary function of Peptide YY is to signal satiety, or fullness, to the brain作者：G GOMEZ·2006·被引用次数：14—Peptide YY(PYY) is a 36-amino-acid peptide hormone produced primarily in enteroendocrine L cells of the distal intestine.. Upon release into circulation, PYY travels to the hypothalamus, a region of the brain that controls appetite.作者：S La Rosa·2022·被引用次数：1—Peptide YY (PYY) is a 36-amino acid peptide encoded by the PYY gene, first discovered in 1982 when it was isolated from porcine intestinal tissue. Here, it binds to specific receptors, notably the neuropeptide Y2 receptor, to inhibit hunger signals and promote a feeling of being satisfied. This action contributes to reducing food intake after a meal.
Beyond its role in appetite regulation, PYY also influences several other gastrointestinal processes:
* Gastrointestinal Motility: PYY can help slow down the movement of food through the digestive tract, allowing for more efficient nutrient absorption.
* Exocrine Pancreatic Secretion: It has been shown to inhibit the secretion of pancreatic enzymes.
* Gastric Acid Secretion: PYY also plays a role in regulating the release of stomach acidPeptide YY (PYY) | Springer Nature Link (formerly SpringerLink).
Given its potent effect on appetite and satiety, Peptide YY has garnered significant interest as a potential target for weight management strategies.2025年8月19日—Peptide YYinhibits transcription and replication of hepatitis B virus by suppressing promoter/enhancer activity. Title: Peptide YY inhibits ... Studies have indicated that individuals with obesity may have altered PYY responses or levels, although this area is still under active research. The administration of PYY, particularly a truncated form known as PYY(3-36), has been investigated for its potential to reduce food intake and promote weight loss.Peptide YY (PYY), human This synthetic version mimics the natural hormone's effect on appetite suppression.作者：MH Tschöp·2007·被引用次数：8—This gutpeptideis a naturally occurring hormone that is secreted by endocrine L cells of the colon (28).

Several factors can influence circulating levels of Peptide YY:
* Meal Composition: High-protein meals appear to stimulate the greatest release of PYY, followed by fatty meals.Isolation and characterization of peptide YY (PYY), a ... Carbohydrate intake also triggers PYY release, but generally to a lesser extent.Peptide YY (3-36): Uses, Interactions, Mechanism of Action
* Nutrient Ingestion: The mere presence of nutrients in the gastrointestinal tract is the primary trigger for PYY secretion作者：BJ Gheller·2019·被引用次数：12—Peptide YY (PYY) is considered a gut peptide with roles in post-prandial appetite and glucose regulation. Circulating PYY protein levels ....
* Gut Microbiota: Emerging research suggests that the gut microbiome may also play a role in modulating PYY production and function.Peptide YY (PYY), also known aspeptide tyrosine tyrosine, is a peptide that in humans is encoded by the PYY gene.
Peptide YY often works in concert with other gut hormones involved in appetite regulation and metabolism, such as GLP-1 (glucagon-like peptide-1). Both PYY and GLP-1 are released from L-cells and contribute to post-meal satiety. Understanding these complex hormonal interactions is key to comprehending the body's intricate system for managing energy balance.
Peptide YY (PYY), or peptide tyrosine tyrosine, is a vital gut hormone with a primary role in signaling satiety and reducing appetite. Produced mainly in the distal intestines, it influences digestion and has become a key area of research for its potential in addressing obesity and related metabolic disorders.作者：G GOMEZ·2006·被引用次数：14—Peptide YY(PYY) is a 36-amino-acid peptide hormone produced primarily in enteroendocrine L cells of the distal intestine. As research continues, a deeper understanding of PYY will likely yield further insights into its multifaceted contributions to human health.
