How peptide classes work

Most research peptides fall into a handful of families, each defined by the receptor it binds and what that binding triggers. Learn the class and you already understand most of what any single compound inside it does.

A peptide is a short chain of amino acids that behaves like a signalling molecule: it docks onto a specific receptor and sets off a downstream response. Compounds that share a receptor, and the cascade behind it, share a research profile. That is why these docs are organised by family rather than by product name.

Classes, not compounds

Once you know which receptor a peptide targets, you can predict the broad strokes of how it behaves. Two incretin agonists work through the same gut-hormone pathway; two GHRH analogues both nudge the pituitary. The class tells you the mechanism, the half-life range, and the kind of research questions a compound is studied for. The individual compound just fine-tunes selectivity, potency or stability within that frame.

The families at a glance

The catalogue and these docs group everything into five mechanistic families. Each has its own page.

Reading the catalogue

Every product on the store maps to one of those five families. The class is the quickest way to understand what a compound is studied for, before you ever look at a molecular weight or sequence.
