{"product_id":"glp1-s","title":"GLP1-S (Semaglutide)","description":"\u003cp\u003eGLP1-S (Semaglutide) is a synthetic 31-amino acid peptide analog of the endogenous incretin hormone glucagon-like peptide-1 (GLP-1). First developed in the 2010s, it is structurally based on native GLP-1 (7–37) with key amino acid substitutions and modification at position 26, where a fatty diacid chain is attached via a spacer to promote strong reversible binding to albumin. These modifications significantly increase resistance to enzymatic degradation by dipeptidyl peptidase-IV (DPP-IV) and extend its half-life.
