A non-opioid peptide derived from adrenal proenkephalin has been isolated and sequenced. The sequence of this peptide is Ser-Pro-His-Leu-Glu-Asp-Glu-Thr-Lys-Glu-Leu-Gln (Proenkephalin 168-180). This sequence represents the portion of Peptide I that is cleaved to yield Peptide E. This peptide is processed in a similar manner to the opioid peptides and is present at approximately the same level as Peptide E.
一种源自肾上腺前脑啡肽的非阿片肽已被分离并测序。该肽的序列为Ser-Pro-His-Leu-Glu-Asp-Glu-Thr-Lys-Glu-Leu-Gln（前脑啡肽168-180）。该序列代表肽I中被切割以产生肽E的部分。这种肽的加工方式与阿片肽类似，且其含量与肽E大致相同。
