The Basics

How Peptides Work

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 research 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 research to model targeted biological responses without the broader off-target effects seen with small-molecule compounds.
