Semaglutide is a synthetic 31-amino-acid peptide — an acylated analog of human glucagon-like peptide-1 (GLP-1) in which the position-2 residue is substituted with 2-aminoisobutyric acid (Aib) and a C18 fatty-diacid chain is conjugated to a lysine side chain through a γ-glutamate and short PEG spacer. Classed as a GLP-1 receptor agonist, it has been investigated in published preclinical and clinical literature for its role in glucose-regulation and metabolic research. Supplied lyophilized at ≥99% HPLC purity with a per-lot Certificate of Analysis. For laboratory and research use only — not for human or animal consumption. ROEHN makes no claims regarding its effects.
