Short chains of amino acids administered therapeutically to modulate specific physiological functions by interacting with cellular receptors or signaling pathways. These agents function as highly specific signaling molecules designed to influence processes like growth hormone release, tissue repair, or metabolic signaling. They represent a precise tool for targeted endocrine modulation. We utilize these to elicit specific, predictable cellular responses.
Origin
The term originates from biochemistry and synthetic biology, focusing on naturally occurring regulatory molecules that govern intercellular communication. Their application in wellness science leverages their high specificity and often favorable pharmacokinetic profiles compared to larger protein hormones.
Mechanism
The mechanism depends entirely on the specific peptide sequence, which dictates its target receptor. For example, certain peptides act as secretagogues, stimulating the pituitary to release endogenous growth hormone, thereby activating the IGF-1 axis systemically. Others may directly influence insulin signaling or modulate inflammatory cascades at the cellular membrane. The action is one of precise signal amplification or dampening at the molecular level.
