Humans and commonly studied lab animals (mice, rats) produce a 27-residue peptide that does not have an amidated C-terminal residue; this is due to the absence of a Gly in the precursor sequence and replacement with Ala, which is not a substrate for the amidating enzyme (Peptidyl-glycine alpha-amidating monooxygenase). The properties of the 27-residue peptide are presumably similar to those of amidorphin, although this has not been adequately tested.

In some brain areas, amidorphin is extensively further reduced into smaller fragments, such as the non-opioid peptide ], or in humans, amidorphin-8-27. Cleavage of amidorphin into these smaller fragments releases the ] -enkephalin]] ] of amidorphin.<ref name="pmid3456613">{{cite journal | vauthors = Liebisch DC, Weber E, Kosicka B, Gramsch C, Herz A, Seizinger BR | title = Isolation and structure of a C-terminally amidated nonopioid peptide, amidorphin-(8-26), from bovine striatum: a major product of proenkephalin in brain but not in adrenal medulla | journal = Proceedings of the National Academy of Sciences of the United States of America | volume = 83 | issue = 6 | pages = 1936–1940 | date = March 1986 | pmid = 3456613 | pmc = 323199 | doi = 10.1073/pnas.83.6.1936 | doi-access = free | bibcode = 1986PNAS...83.1936L }}</ref>
