Peptide science, explained clearly

Careful, jargon-free writing on the fundamentals — from what a peptide is to reading a Certificate of Analysis.

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.

Research Library

Neutral, informational profiles of peptide research compounds — presented for education, not for sale.

Triple incretin receptor agonist (investigational)

An investigational synthetic peptide studied as a triple agonist of the GIP, GLP-1, and glucagon receptors in metabolic research.

Synthetic peptide related to Thymosin β-4

A synthetic peptide associated with the actin-binding region of Thymosin β-4, studied in cell-migration and tissue-repair research models.

Body Protection Compound-157 (pentadecapeptide)

A synthetic pentadecapeptide derived from a sequence identified in gastric juice, studied in cytoprotection and tissue-repair research models.

Lysine–Proline–Valine tripeptide

A tripeptide corresponding to the C-terminal sequence of α-MSH, studied within anti-inflammatory signaling research.
