WebAdrenocorticotropic hormone (ACTH) is a hormone that stimulates the adrenal cortex to produce cortisol. It is produced by the hypothalamus and released into the blood by the pituitary gland. Adrenocorticotropic hormone is responsible for regulating many bodily functions, including stress response, energy balance, carbohydrate metabolism, and ... WebACTH is derived from the cleavage of POMC by proprotein convertase-1. 5–9 ACTH binds to steroidogenic cells of both the zona fasciculata and reticularis, activating adrenal steroidogenesis. It also has a trophic effect on adrenal tissue; therefore, ACTH deficiency determines adrenocortical atrophy and decreases the capacity to secrete glucocorticoids.
