Glucagon-like peptide-1 (GLP-1) is a 30- or 31-residue peptide hormone released from enteroendocrine L cells of the distal small intestine and colon in response to nutrient ingestion. It is one of the two principal incretin hormones, the other being Glucose-dependent insulinotropic polypeptide (GIP).[1]
GLP-1 is generated by tissue-specific post-translational processing of proglucagon, the same precursor that yields glucagon in pancreatic alpha cells. In the intestine, prohormone convertase 1/3 liberates GLP-1 (7–37) and its C-terminally amidated form GLP-1 (7–36) amide, the latter accounting for the majority of circulating immunoreactive GLP-1 in humans.[2]
