Talk:Vitamin A
From Wikipedia, the free encyclopedia
[edit] not a disambig page
The disambig template reads:
 |
This disambiguation page lists articles associated with the same title. If an internal link led you here, you may wish to change the link to point directly to the intended article. |
which this page clearly doesn't do.
I'm not sure why this is a disambig page. Vitamin C, Vitamin D, etc are all full articles. The B vitamins are chemically distinct, so it makes sense to have that page structured as it is. Are the "A vitamins" chemically distinct? I imagine that Retinol and other Retinods are similar. That is, is it even proper to say the "A vitamins"? Does it make sense that a page, like Antioxidant, would link to retinol rather than Vitamin A?
I propose that this page no longer be considered a disambig page. The disambig template should be removed, and the article on Vitamin A, in all forms, should be expanded (or simply allowed to expand).
Perhaps it could be marked a stub? Alternately, it should state that "When people refer to Vitamin A, they usually mean blank..." — baisically turning this short list into a short pargraph. Still, it shouldn't be a disambig page.
Any thoughts?

- I was the one who turned this page into a disambig page. Basically I did it because I thought "retinol" was overly specific -- from a nutritional standpoint, you can get vitamin A from plant foods, but you can't get retinol from them, unless someone happens to have smeared them with liver :-). Anyway I kind of agree with you that this isn't the best solution as it stands -- most of the information at retinol really belongs at vitamin A, except for the purely chemical stuff. See talk:Retinol#Vitamin A redirects here; should it? and add your two cents. --Trovatore 04:47, 21 December 2006 (UTC)

Why is there a link to this page titled "Vitamin A overdose"? --Connel MacKenzie - wikt 02:11, 1 January 2007 (UTC)
[edit] Pharmacological definition of Vitamin A
Perhaps this article could provide at least one link to a scientific paper that expounds the pharmacological definition. As a start, I found this short definition on the web:
"Pharmacology: The term vitamin A is applied to a number of substances with very similar structure and similar activity. The principal and most active substance is all-trans retinol (vitamin A alcohol). Vitamin A activity is assayed biologically and 1 IU equals 1 USP unit which is equal to 0.3 µg of all-trans retinol or 0.6 µg of beta-carotene. One retinol equivalent (RE) is the specific biologic activity of 1 µg of all-trans retinol (3.33 IU) or 6 µg (10 IU) of beta-carotene."
