Talk:Thyroid hormones

message: A large number of statements give precise information which I presume, or references suggest, is applicable to humans. I think this should be made explicit, the hormone is common to all mammals, I believe all vertebrates(?), and some invertebrate (e.g. Lampreys cf: endostyle). Almost all multicellular animals and many plants use Iodine containing compounds for related purposes.  — Preceding unsigned comment added by 84.45.158.52 (talk) 20:44, 28 June 2011 (UTC)

thread_title:  Mispelling? 

message: It has been suggested that triiodothyronine be merged into thyroid hormone.  I believe they should not be merged.  We have a rule at WP:CHEMS - one article per chemical compound.  Triiodothyronine is a single compound and thus should remain a separate article from thyroxine.
The thyroid hormone article is fine, but there should be separate articles for each of the compounds mentioned - there needs to be a chembox for each one, where data such as molecular formula are available.

text: I also think these two compounds deserve their own article. Since it's been agreed upon for about two months that the merger should not go ahead, I'm removing the requests to merge. KBi 04:42, 12 April 2007 (UTC)
replies: text: This was a bad idea. Thankfully, the triiodothyronine article is still there - with useful and interesting chemical information unrelated to thyroid tests and function. The Thyroxine article should be put back. There is little useful chemical information here for thyroxine - and there should not be - it belongs in a restored levothyroxine page.

message: Is there some valid reason that the two molecular diagrams are rendered differently? Or is it just that they came from different sources?
Looking at triiodothyronine and thyroxine bond by bond, I seem to find that they differ by exactly one iodine atom. This would be quite obvious if they were oriented in the same way and used similar conventions for the bonds in the neighborhood of the amine group. Not a big deal, of course, but there's a failure of clarity here; unless, that is, the different drawings are expressing some actual chemical difference beyond a one-atom substitution.

thread_title:  Scope of WP:PHARM 

message: The following biochemical image is moved here to Talk, as it lacks a legend, its labels are not mentioned in the text, and when the text addresses the matter of deiodinases, it uses different terms distinct from those appearing in the image labels (the labels IDI, IDII, outer ring, etc. do not appear in the article). Hence, even to a well-educated reader, reading the text and image in the context of one another is confusing. On return of the image to the article, please rectify the issues with regard to stand-alone understandability, and also create a ... entry citing the source of the information that the image represents (since in honest academic work—see —at Wikipedia or otherwise, use of images is not supposed to be a means to circumvent having to give attribution/recognition of sources of information.

thread_title:  Featured picture scheduled for POTD 

message: My recently acquired (and imperfect) knowledge tells me that T3 is a hormone and T4 is a prohormone.  T4 binds weakly at the receptor.  The body's strategy is to pump out the relatively inactive T4 from the thyroid, and then convert T4 to T3 where the hormone is needed.  If this scenario is true, the article might be relabeled as thyroid hormone (singular).  
Furthermore, the article would need to be "reconciled" with an existing article on T3, levothyroxine.  Otherwise we have to maintain two articles.  Of course, we maintain lots of somewhat parallel articles often, but this case is perhaps more critical since this hormone, both natural and synthetic, is so widely used (7% of US population according to my source).  So we want a one-stop shopping site that is closely managed.--Smokefoot (talk) 18:57, 21 May 2023 (UTC)

thread_title: Thyroid hormones or Thyroid hormone? (singluar)

message: I propose to merge levothyroxine into Thyroid hormones (or preferably Thyroid hormone (see discussion above).
The logic:
#Levothyroxine is T3.
# T3 is the focus of  Thyroid hormones and levothyroxine.
# As one of the top prescribed drugs (#2 in the US according to my sources), we cannot mess around with readers, we need one masterpiece on this topic.  If the topic were unimportant, we wouldn't care.

replies: text: I find it reasonable to have one article focusing on thyroid hormone(s) as endogenous hormone(s) and one focusing on the drug. It may be named to better reflect this usage, such as Thyroid hormone (drug). Mikael Häggström (talk) 02:48, 23 May 2023 (UTC)
