GLP-1 (Glucagon-Like Peptide-1)

An incretin hormone produced by intestinal L-cells in response to food intake. GLP-1 stimulates insulin secretion, inhibits glucagon release, slows gastric emptying, and promotes satiety through central nervous system signaling. Research into GLP-1 receptor agonists has led to significant developments in the study of metabolic conditions, with compounds like semaglutide and tirzepatide being among the most extensively researched peptides globally.
