A peptide that functions as a biological messenger, binding to cell receptors to regulate processes such as appetite, fluid balance, and endocrine function. Examples include GLP-1, oxytocin, and kisspeptin.
"Signaling Peptide" is filed under Basics in the PeptideAtlas glossary, alongside 12 other terms in that group.
The term applies directly to 1 compound profile here: Palmitoyl Tripeptide-1 (evidence F). Each profile states the strength of the human evidence rather than only what the compound is claimed to do.
The building blocks of peptides and proteins. There are 20 standard amino acids that combine in various sequences to form peptides.
A short chain of amino acids (typically 2-50 amino acids) linked by peptide bonds. Shorter than proteins but with diverse biological activities.
The chemical bond formed between two amino acids when the carboxyl group of one reacts with the amino group of another, releasing water.
Compounds where this applies: Palmitoyl Tripeptide-1.
