Talk:Chemistry of ascorbic acid

message: An anonymous user amended this from 176.12 to 176.13
Both weights give a similar number of hits on Google however since a large proportion of the 176.12 sites are Wikipedia mirror ones I've left the higher figure. Can anyone give an authorative answer?  Lumos3 15:33, 26 Sep 2004 (UTC)
replies: text: Using the numbers for atomic weight given on wikipedia for carbon (12.0107), Hydrogen (1.00794), and Oxygen (15.9994), it's 176.12412, which would be the same as 176.12, so I edited it back. --Niffux 06:43, 20 Oct 2004 (UTC)

message: I'm curious since the molecule doesn't have any obvious "acid" component.  Does the ring get hydrolyzed, leaving a carboxyl group? GCarty 08:57, 18 July 2005 (UTC)
thread_title:  Which is the "acid" hydrogen? 

message: Polyparadigm- I do have infomation on the synthesis of Vitamin C in about 10 different methods, though im not really sure about copyright on the images i would need to explain it.
GCarty - The OH groups  on the 'bottom' of the molecule are easily oxidised and the H+ are dissociated into solution, giving the acid, acidic preoperties.
(usually only 1 H+ dissociates forming dehydroascorbic acid, therefore its is only a weak acid) the remaining oxygen form a double bonds with the carbon (a carbonyl group like you mentioned)

thread_title:  Merge [[Erythorbic acid]] into this article? 

message: Why is there nothing in the article about L-ascorbic acid and D-ascorbic acid?  I mean it is a big deal, two totally distinctly different seperate sides of Ascorbic Acid, and there's nothing about this in the article...  Like how research shows the body disregards D-ascorbic acid (+) and only uses L-ascorbic acid (-).  Or at least anything regarding the 2 different and seperate sides of ascorbic acid.  Does anyone think something regarding this topic should be put in the article?

replies: text: If you are talking about :File:AscorbicAcid acidity.svg, it appears to be correct to me.  There are six oxygen atoms in each molecule.  Maybe it was wrong at some point, but I just wanted to point out that it is now correct.  ChemNerd (talk) 15:26, 1 March 2012 (UTC)

thread_title:  Ascorbic Acid Made By Boiling Corn Syrup in SuLphuric Acid? 

message: The article statues that
    "There exists a D-ascorbic acid"
without any explanation of what that means.  I gave up chemistry several decades ago, and would (have) appreciate(d) a hint/reminder of what is going on.
Looking on THIS page, I think it is related to being a different isomers.  So something as simple as....
    "There also exists D-ascorbic acid, a stereoisomer of the XXX L-ascorbic acid."
where XXX should be something like "better known", "more common", "first discovered", "more important"....
And, of course, Stereoisomer should be a link to the relevant page/article...

But not every other Wikipedia have 2 distintc articles. The only one may be linked to one of the WikiData items or the the other one. So it's a very  muddled situation. --Mezze stagioni (talk) 12:54, 9 April 2020 (UTC)

replies: text: "Two articles on different specific aspects of a topic" is not uncommon. Nor is it uncommon for some languages' wikipedias to have made that fork while others have not. It is up to those other wikipedias that have only a single article to decide which wikidata item is more appropriate for the scope of their article. An alternate solution would be for them to split their article into the same two subarticles, so that they can each have the correct wikidata link.
