Peptide Glossary — Reference Terms¶

A–C¶

Amino Acid — Building block of peptides; 20 standard types. cAMP — Second messenger produced by adenylyl cyclase; key readout in GPCR assays. CAS Number — Unique numerical identifier for chemical substances. COA (Certificate of Analysis) — Quality document summarizing batch analytical results.

D–G¶

DPP-4 — Enzyme that degrades incretin peptides; resistance improves stability. GCGR (Glucagon Receptor) — Receptor for glucagon; involved in glucose homeostasis and energy expenditure. GIPR — Receptor for glucose-dependent insulinotropic polypeptide. GLP-1R — Receptor for glucagon-like peptide-1; key incretin target. GPCR — G protein-coupled receptor family.

H–R¶

HPLC — High-performance liquid chromatography for purity analysis. Incretin — Gut hormone that potentiates insulin secretion. LC-MS — Liquid chromatography-mass spectrometry for identity confirmation. Lyophilization — Freeze-drying process; produces stable peptide cake. MOQ — Minimum order quantity.

S–Z¶

SPPS — Solid-phase peptide synthesis. TFA — Trifluoroacetic acid; residual counterion from HPLC purification. Triple Agonist — Peptide activating three receptor targets simultaneously. UPLC — Ultra-performance liquid chromatography.
