GLP-1 (glucagon-like peptide-1, 7-37) is the biologically active form of the endogenous incretin hormone glucagon-like peptide-1, derived from proglucagon cleavage. With the molecular formula C₁₅₁H₂₂₆N₄₀O₄₆ and a molecular weight of 3337.73 g/mol (CAS: 106612-94-6), it is a 31-amino-acid peptide studied in pancreatic beta-cell and incretin-pathway models for its interactions with the GLP-1 receptor and downstream Gs-protein coupled cAMP signaling.
