Glucagon-Like Peptide-1 (7-37) is a naturally occurring, biologically active form of GLP-1, a hormone derived from the proglucagon gene. It consists of 31 amino acids and plays a key role in glucose homeostasis. GLP-1 (7-37) stimulates insulin secretion in a glucose-dependent manner, inhibits glucagon release, slows gastric emptying, and reduces appetite, making it important in the regulation of blood sugar levels and a target for type 2 diabetes and obesity treatments.
