Semaglutide is a synthetic lipidated peptide of thirty-one amino acid residues and, by receptor class, a GLP-1 receptor agonist peptide. Two modifications distinguish it from an unmodified chain. Position 2 is α-aminoisobutyric acid (Aib), a non-proteinogenic residue with two methyl groups on its α-carbon. The side chain of the lysine at position 20 carries an octadecanedioic (C18) diacid, attached through a γ-glutamic acid residue and two short ethylene-glycol-based spacer units. The C-terminal residue is a glycine with a free carboxylic acid.
The catalogue lists CAS number 910463-68-2, the molecular formula C187H291N45O59 and a molecular weight of 4113.58 g/mol. Identity is confirmed by electrospray mass spectrometry, deconvoluted from multiply charged ions to a neutral mass, and reversed-phase HPLC gives the chromatographic profile. Each presentation is supplied as a lyophilised powder in a sealed vial.
