Talk:Opioid peptide

Opioid peptides of microbial origin

It would be good to have references cited for this part. Could this be from Kreil G (1994). "Peptides containing a D-amino acid from frogs and molluscs ?

Chapter name could also be chaged since Deltorphin and Dermorphin can also be found from Phyllomedusa bicolor frog.Ahabvihrea (talk) 00:58, 4 May 2008 (UTC)

Reference for attachment behaviour claim?

I'd really like to see one for this. I'm certain it's true from experience but never got any backing on it. 74.78.116.93 (talk) 22:46, 3 January 2009 (UTC)

I remember reading a paper a long time ago in the prairie vole literature regarding the reward system and pair bonding - possibly this one. However, this study didn't find any drug effects when either montane or prairie voles were given naloxone, which would cast doubt on the role of endogenous opioids in attachment behavior. Perhaps the systems simply overlap [1]? St3vo (talk) 23:33, 3 January 2009 (UTC)

Relationship to Serotonin?

I vaguely recall reading that serotonin and OGF opioids in general are linked to serotonin. Any thoughts? — Preceding unsigned comment added by 176.61.28.141 (talk) 23:13, 12 February 2013 (UTC)

Thesis Statement Needed

This article was over my head before the first sentence was over, it is useless for someone who wants to learn about the subject. For the first sentence, try writing a complete overview of the article using nothing more than the the first hundred or so simplest English words. The details are great, but you must lead into them.

Endomorphins > beta-endorphin

the affinity of endomorphins for the mu opioid receptor is greater than that of beta-endorphin (endomorphins: high picomolar, beta-endorphin: low nanomolar). Therefore the ‡ sign should be used for endomorphins and not beta-endorphin. I do not have the time to properly edit so I'm not doing it myself... — Preceding unsigned comment added by 77.136.84.112 (talk) 19:53, 19 February 2019 (UTC)
