Biology & mechanism

A first-generation acylated GLP-1 analog. A palmitic acid chain confers albumin binding and a roughly 13-hour half-life, permitting daily dosing. Mechanism otherwise parallels semaglutide: glucose-dependent insulin secretion, glucagon suppression, delayed gastric emptying, central appetite reduction.
