Our bodies create peptides from diet and from natural physiological processes. Our ability to produce and process complex peptides is dependent on various factors, including nutrition, stress, and age. For example, IGF-1 is a very important peptide that helps modulate cellular metabolism. When we get older, the body doesn't produce IGF-1 as efficiently. The production of this peptide is also sensitive to stress. What Do Peptides Do? Peptides have many vital roles in normal human physiology. Many peptides are precursors to complete Hormones like HGH. Some interact with the endocrine system as Hormones, others modulate the nervous system as neurotransmitters. … Continue reading →

Pancreatic Peptide YY is one of many hormones involved in digestive activity. It is produced by L-cells along with a handful of other hormones. These cells are primarily located in the ileum and colon. Also referred to simply as Peptide YY, this important hormone is released in response to eating. Peptide YY is responsible for sending signal from the digestive tract to the brain in order to signal the feeling of fullness. When Peptide YY acts on the brain, it induces the sensation of fullness and suppresses appetite. Peptide YY also operates within the digestive system itself, slowing down the … Continue reading →
