A useful mental model: amino acids are letters, peptides are short messages, and proteins are longer instructions.
A peptide is a short chain of amino acids. Many peptides act like biological messages, interacting with receptors or pathways and influencing what happens next.
Different amino-acid sequences have different shapes and can interact with different biological targets.
“Peptide” is a broad category—not a guarantee that every compound has the same safety, approval, or research profile.

THE LANDSCAPE
Researchers group compounds by the systems and pathways they study—not simply by the outcomes promoted online.
