The molecule is a synthetic peptide that is identical to the 24-amino acid segment at the N-terminal of adrenocorticotropic hormone (corticotropin). A segment similar in all species, it contains the biological activity that stimulates production of corticosteroids in the adrenal cortex. It is used diagnostically to investigate adrenocortical insufficiency. It has a role as a diagnostic agent.
