Emotion

curious to know more about how peptides affect emotion as suggested in What the bleep do we know. —Preceding unsigned comment added by DennisDaniels (talk • contribs) 04:57, 20 August 2004

I suggest reading Candace Pert's work, especially this book:

Molecules Of Emotion: The Science Behind Mind-Body Medicine, Scribner, 1999, ISBN 0-684-84634-9

Also, you can read about her work on this website. There are some podcasts that might interest you. Renee (talk) 19:18, 6 June 2008 (UTC)[reply]

Peptide hormones or protein hormones?

How common is it to distinguish between "protein hormones" (such as follicle-stimulating hormone, parathyroid hormone, prolactin and thyroid-stimulating hormone) and "peptide hormones" depending on the length of the amino acid chain? As the article is written now (and many others, and Category:Peptide hormones), "peptide hormones" more or less seems to cover all amino acid chains with hormonal activity regardless of length. If this is indeed the case, it would be helpful to point out in the article that some peptide hormones aren't peptides in the narrow sense. If the reverse is true, a clearer distinction should be made in this article (although I guess both could still be described in the same article) and the category renamed to "Peptide and protein hormones" or somesuch. //Essin (talk) 20:44, 5 August 2010 (UTC)[reply]

Odd wording

Right now the article states this:

"When a peptide hormone binds to a receptor on the surface of the cell, a second messenger appears in the cytoplasm, which triggers signal transduction leading to the cellular responses."

But this makes it sound as if the second messenger magically just "appears" in the cytoplasma. This can not possibly be. Biology does not magically conjure molecules out of nowhere.

So I suggest it should be reworded, e. g. briefly mention HOW the second messenger is effected within the signal cascade - be it release from some depot, or some enzyme that acts and so forth, rather than assuming magic here. 2A02:8388:1641:4980:480D:4D4E:3D5F:4D8C (talk) 13:09, 28 June 2023 (UTC)[reply]
