Adrenocorticotropic Hormone (ACTH) (18-39), also known as the Corticotropin-like Intermediate Lobe Peptide, stimulates insulin secretion as well as amylase and protein secretion in a dose-dependent manner similar to secretin and carbamylcholine.
Adrenocorticotropic Hormone (ACTH) (1-39), rat, is a potent melanocortin 2 (MC2) receptor agonist. During in vitro incubation with membrane preparations, peptide fragments of ACTH (1-39) were formed and subsequently isolated by high-pressure methods.
