Semaglutide

GLP-1 Receptor Agonist Modified Polypeptide

Semaglutide is a synthetic glucagon-like peptide-1 (GLP-1) receptor agonist modified with an alpha-aminoisobutyric acid substitution and a C-18 fatty diacid spacer to facilitate non-covalent albumin binding. Characterized across human clinical trials for glucose regulation and neuro-endocrine appetite pathway interactions.
