Talk:Adenine

message: This structure is incorrect.  There should not be a double bond to the extracyclic amino group, but rather to the N in the ring (unless we want a bizarre resonance structure, but in that case we would need charges on the nitrogens).

text: I agree with Josh. In my opinion, it is better to have no diagram than an incorrect diagram. Axl 18:58, 14 Dec 2004 (UTC)
thread_title: Chemical structure

message: Is this a real vitamin or not?  I assume it's not: It's not listed on the vitamin page, and that page is quite explicit that there are only thirteen recognized (human) vitamins.  But this page is also listed under category:vitamins.
It was considered one, once upon a time, but it turns out it isn't. Kr5t 02:14, 21 May 2006 (UTC)
thread_title:  Vitamin? 

message: Well, the diagram is wrong. I dont know what the right one looks like, but this doesn't have H5. Also, I think it's important to include other common biological molecues that have Adenine in them. This includes, but is not limited to NAD, NADH... yeah. Can't think of anymore off the top of my head but it's a start.
:What's wrong with the structure?  You mean that it doesn't have five hydrogens?  It does.  Two of them are implicit, according to the well established conventions for drawing structures (each of the two carbon atoms that would otherwise form only three bonds has a hydrogen substituent that's not explicitly shown).
:There are tons of biochemicals that contain an adenine moiety.  I don't think we should show all of their structures here. Josh Cherry 01:19, 11 Feb 2005 (UTC)

message: In the article, it said that Adenine could form a base pair with thymine, but it also forms a base pair with uracil. Dogmanice 18:45, 19 March 2006 (UTC)
thread_title:  Part in article was wrong 

message: The diagram of adenine to the left of the text appears to inconsistent with that which appears on the right of the text (in the box with the SMILES and CAS number and other info). I recognize it as tautomers (correctly, I hope), but shouldn't we make a note of it? I hadn't even heard (read) of tautomers until earlier today, when I was studying SMILES.

message: The way that the word cytoplasm is used in this article shows a bias against prokaryotic cells. By mentioning cytoplasm only at the RNA to protein step it suggests that the RNA is not generated in the cytoplasm but in a different structure.  This is true for only a tiny fraction of all known lifeforms. Hcobb (talk) 00:08, 12 June 2009 (UTC)

message: I think this article should include examples of types of food that contain this vitamin. Any thoughts on that?

message: Out of interest more than for scientific value, I considered adding this image of adenine from the Watson Crick model, with this caption. But then I looked on the Science Museum's flickr page from whence it came, and saw they labelled it as thymine despite the A (and the structure). This is obviously wrong, but I thought I'd mention it on here for discussion before I posted it. Assuming it is adenine, any ideas why the NH2 group at left seems asymmetrical? I presume this (and the long line at centre-left) are meant to show the hydrogen bond. Blythwood (talk) 23:39, 12 November 2015 (UTC)

thread_title: Assessment comment

message: I removed the following paragraph because its beginning repeated what was said in the previous paragraph, and the rest was not so much about adenine biosynthesis as about less specific ideas on the role of inosine monophosphate in relation to the other purines and carbon-based life in general.  These ideas, if expressed more crisply, might be better as a part of the articles on Inosine monophosphate or Purine metabolismCharlesHBennett (talk) 19:11, 17 December 2019 (UTC)
