A primer on peptide science, mechanisms, and terminology for newcomers — short chains of amino acids capable of highly specific biological signaling.
The Basics
Peptides are short chains of amino acids linked by peptide bonds — smaller and simpler than full proteins, but capable of highly specific biological signaling. In settings, synthetic peptides are used to study cellular mechanisms, receptor activity, and metabolic pathways.
Peptides interact with specific receptors on cell surfaces, triggering downstream signaling cascades. Because of their structural specificity, they are widely used in laboratory work to model targeted biological responses without the broader off-target effects seen with small-molecule compounds.
