GLP-1(S)

What is Semaglutide?
Semaglutide is a synthetic analog of human glucagon-like peptide-1 (GLP-1) with 94% homology to native GLP-1. With the molecular formula C₁₈₇H₂₉₁N₄₅O₅₉ and a molecular weight of 4113.6 g/mol (CAS: 910463-68-2), Semaglutide incorporates a C18 fatty di-acid side chain attached to lysine at position 26 and modified amino acid substitutions at positions 8 (Aib), 34 (Arg), and a truncated C-terminus.

Mechanism of Action
GLP-1 Receptor
Gs-protein couplingSemaglutide binds to GLP-1 receptors with high affinity, activating Gs-proteins and increasing intracellular cAMP levels in beta-cell models.
Albumin Binding
Lipophilic side chain interactionThe C18 fatty di-acid side chain enables reversible albumin binding, extending circulation half-life in biochemical studies.
Receptor Internalization
Endocytosis/recyclingPublished studies indicate Semaglutide promotes receptor internalization with distinct kinetics compared to native GLP-1.
