Handling & reference
- Kisspeptin-10 — what the (45-54) in the name meansKisspeptin is a family, not a molecule. The number after the name tells you which fragment is in the vial, and the fragments differ by thousands of daltons.
- PT-141 (Bremelanotide) — a cyclic peptide, and why that mattersBremelanotide is cyclised head-to-side-chain, not linear. The ring changes its stability, its analysis, and what a COA can and cannot confirm.
