Synthesis, purity verification, and structural chemistry of research peptides.
A research reference on the chemistry of tirzepatide — a 39-amino-acid dual GIP/GLP-1 receptor agonist — covering sequence architecture, fatty-acid conjugation, and HPLC-grade verification considerations.
The triple-incretin (GLP-1 + GIP + glucagon receptor co-agonist) class is the fastest-growing reference-peptide research segment going into 2026. Here is a chemistry-first walkthrough for research chemists deciding whether to add a triple-incretin reference standard to their catalog. From single…
MOTS-c is a 16-amino-acid mitochondrially-derived peptide with unusual chemistry. A primer on sequence, synthesis, and how it is characterized for research use.
The coordination chemistry of GHK-Cu and related copper(II) tripeptide complexes — structure, synthesis, stability, and how research-grade material is verified.
The chemistry of GLP-1 (glucagon-like peptide-1): 31-amino-acid sequence, receptor family, structural biology, and how GLP-1 reference standards are characterized.
A practical chemistry walkthrough of the two dominant solid-phase peptide synthesis strategies — Fmoc and Boc — and why modern reference-grade peptides use Fmoc.
What the "99% HPLC purity" figure on a Certificate of Analysis actually means, how it is measured, and why it matters for peptide reference standards.
A chemistry-first overview of BPC-157 — the pentadecapeptide sequence, Fmoc solid-phase synthesis, mass-spec confirmation, and how U.S.-manufactured reference standards are verified.
