Adrenocorticotropic hormone (ACTH) is a polypeptide hormone that exists principally as a chain, 39 amino acid long, with a molecular mass of approximately 4,500 daltons. It is produced in the pituitary and serves to stimulate steroid production by the adrenal cortex. ACTH secretion is in turn controlled by the hypothalamic hormone corticotropin releasing factor (CRF) and by negative feedback from cortisol.
