The chemical structure image file of purine had to be modified anyway because there was a missing electron pair on the #3 atom (a nitrogen). I took the then-existing image file, made the electron pair correction, and moved the "colored ball" picture of the molecule down below the other purine structures so the picture would be less wide. The previous width of the picture made the table wide, which unsatisfactorily compressed the text to the left of it. This new arrangement looks better on my computer screen. It does not hide any information in the purine-pyrimidine base "chart" for DNA. I use America OnLine (AOL) which by default makes the Wikipedia row span about 538 - 540 pixels wide. I'm sure many other readers/users of Wikipedia get a similar view of a Wikipedia page, although some other internet users may get a wider screen view and may not realize the "compressed text" problem. I anticipate that this picture modification will not adversely affect these other users. A similar problem exists for other Wikipedia articles on "Simple aromatic rings". I can similarly change those pictures too to produce less wide, better-looking tables. H Padleckas 10:01, 9 Apr 2005 (UTC)
Better resize the images. Sooner or later I will produce high resolution variants to be uploaded to the Wikimedia Commons. Cacycle 23:55, 9 Apr 2005 (UTC)
Hm, the structure of uric acid here has a hydroxyl group where uric acid has an oxygen group (the hydrogen is moved to an adjacent nitrogen atom). Which one is right? Taral 16:23, 2 September 2005 (UTC)
Both are right, see Keto-enol tautomerism. I don't know which form predominates, though, but I'm guessing it's the one shown in the uric acid article. Anyway it wouldn't hurt to make them match. Molybdenumblue 16:54, 2 September 2005 (UTC)
