What is a peptide?

Peptides are short chains of amino acids — the same building blocks that make up proteins. In the body, they act as signaling molecules: tiny messengers that tell cells to repair tissue, release hormones, regulate metabolism, or modulate the immune system.

Because each peptide targets specific pathways, researchers study them for everything from injury recovery to cognitive support. On PeptideChat you can learn how each one works, what the research says, and how compounds are typically studied — all in clear, approachable language.
