Semaglutide is a synthetic acylated analogue of human glucagon-like peptide-1 (GLP-1). Public reference sources describe a 31-amino-acid backbone with an aminoisobutyric acid substitution at position 8 and a C18 fatty diacid side chain attached through a gamma-glutamyl/AEEA linker, which is associated with albumin binding and an extended plasma half-life. In many jurisdictions semaglutide is a prescription pharmaceutical substance; presence of this identity record does not indicate approval, availability, or eligibility for supply. Purity, impurity profile, peptide content, water content, residual solvents, endotoxin and other quality attributes are batch-specific and are only meaningful when supported by a batch Certificate of Analysis issued against a defined specification. Red Chem Biotech has not published verified analytical values for this record.
