Talk:Uracil

message: Glad to see this article is getting worked on quite a bit, a couple of issues I'd like to mention.  I believe the synthesis section should be moved later in the article.  Uracil is a biomolecule and while synthesis is of interest, the biochemistry is much more important and more likely to be why people look up the article.
The references are nice, but they should be in order.  Right now it goes 1 then 10 then 8, it may be preferable to just make each footnote citation a link to the citation on the bottom instead of numbers (that way they don't have to be constantly changed!)Hichris 03:06, 9 May 2006 (UTC)

message: We should at least explain a little about tautomers and such! In fact, the adenine page has two pictures of tautomers of adenine, a sure source of confusion. I'll add a link to this page, with the observation that it explains alot of tautomers and such, in addition to being a related substance. Kr5t 02:46, 21 May 2006 (UTC)

thread_title: Suppliers links

message: Because there was a dispute about the link to a commercial supplier in this text, I have gone through the text, tried to find where this ref (ref. 2) was.  Since I could not find it, I started to replace the refs with ref-tags, and clean up the section in that way.  Three references are gone, in case I missed some, the old ones are down here:

thread_title:  Old references, cleanup 

message: I don't think so. 1) There's no sulfur in uracil. 2) Sulfur trioxide is highly dangerous.  —Preceding unsigned comment added by 71.178.59.216 (talk) 15:27, 12 November 2008 (UTC)
thread_title:  Fuming Sulfuric Acid?? 

message: There are several errors with the first chemical formula. This is what the article says:
Degradation of uracil produces substrates, aspartate, carbon dioxide, and ammonia:
:C4H4N2O2 → H3NCH2CH2COO- + NH4 + CO2
*The text says ammonia and the formula says NH4.
*There is no such thing as NH4. It should either say NH3 or NH4+.
*It is not balanced. There are, for instance, two oxygen atoms on the left side, and four on the right side.

replies: text: There is no aspartate, but beta-alanine missing it's positive charge. You can't get aspartate out of uracile without adding a carboxylic group to the C3-chain. Nor can you get maleic acid by oxidation without doing the same. Please consider malonic acid in this case. The stoichiometry of the above equation is impossible. --FK1954 (talk) 21:32, 22 September 2013 (UTC)
thread_title:  Chemical formula 

message: "Originally discovered in 1900, it was isolated by hydrolysis  of yeast  nuclein that was found in bovine thymus and spleen, herring  sperm, and wheat  germ"
Why would yeast nuclein be found in bovine thymus and spleen ?   This makes no sense.   Is it a joke ?  Perhaps this sentence should be rewritten.Eregli bob (talk) 19:31, 18 March 2010 (UTC)
thread_title: Strange assertion

message: Hello,
It has been suggested to merge the article "Uracil in DNA" into "Uracil". I completely agree and would like to perform the merging. What do the others think? MultiOlga (talk) 08:29, 24 July 2013 (UTC)
