Peptide science, explained clearly

Careful, jargon-free writing on the fundamentals of peptide biology, analytical quality, and how to evaluate research information critically.

A clear, jargon-free explanation of what peptides are, how they differ from proteins, and why they matter in biology.

Many naturally occurring peptides act as messengers. We look at how signaling works — carefully, without overstating the science.

Amino acids are the building blocks of peptides. Here is what that means and why sequence matters.

An accessible overview of the analytical methods laboratories use to characterize identity and purity.

A COA can look intimidating. We break down each section so you can evaluate documentation critically.

The term is used loosely across the industry. Here is a precise, honest look at what it should — and should not — imply.
