Adrenorphin also sometimes referred to as metorphamide is an endogenous C-terminally amidated opioid octapeptide (Tyr-Gly-Gly-Phe-Met-Arg-Arg-Val-NH2) that is produced from proteolytic cleavage of proenkephalin A and is widely distributed throughout the mammalian brain. It was named based on the fact that it was originally detected in human phaeochromocytoma tumour derived from the adrenal medulla and was subsequently found in normal human and bovine adrenal medulla as well.
