PEPTIDE YY Meaning and
Definition
-
Peptide YY (PYY) is a naturally occurring peptide hormone that is primarily secreted by cells in the distal ileum and colon of the gastrointestinal tract in response to food intake. It is also known as peptide tyrosine tyrosine due to the presence of two tyrosine residues in its amino acid sequence.
PYY plays a crucial role in regulating appetite and satiety by signaling the brain about the body's nutritional status. When released into the bloodstream, PYY acts on specific receptors in the hypothalamus, a region of the brain responsible for regulating food intake, and triggers a feeling of fullness or satiety. This hormonal response helps control food intake and influences the duration between meals.
In addition to its role in appetite regulation, PYY also contributes to the overall regulation of energy balance. It helps to slow down gastric emptying, reducing the speed at which food moves through the digestive system. This effect leads to increased nutrient absorption and utilization, ultimately aiding in the regulation of body weight.
Several factors influence the secretion of PYY, including the macronutrient composition of a meal. High-protein and high-fat foods tend to stimulate PYY release more effectively than high-carbohydrate meals. Additionally, levels of PYY are influenced by factors like stress, exercise, and certain medical conditions.
Understanding the role of Peptide YY in appetite regulation and energy balance is essential for developing strategies to combat obesity and promoting healthy weight management.

Etymology of PEPTIDE YY
The word "Peptide YY" is derived from the scientific term "peptide" and the capital letter "Y" followed by another letter "Y".
- "Peptide" originates from the Greek word "peptikos", which means "digestible" or "able to be broken down", referring to the nature of peptides as molecular chains of amino acids.
- The two "Y" letters in "YY" denote the peptide's origin and discovery. In this case, "Y" stands for Yalow, as the peptide was named in honor of Rosalyn Yalow, an American medical physicist who won the Nobel Prize in Physiology or Medicine in 1977 for her work with the development of radioimmunoassays.
Therefore, "Peptide YY" represents a specific peptide molecule while also acknowledging the scientist who contributed significantly to its discovery.
