:Talk:Urocanic acid

198.202.68.49 left the following comment in the article, which I moved here instead:

:Chemical structure is erroneous in position of one of the nitrogens.

The image currently shown is this one:

And the IUPAC name shown is:

:(E)-3-(1H-imidazol-5-yl)prop-2-enoic acid

One of these is wrong. It must either be:

• 1H-imidazol-4-yl
• 3H-imidazol-5-yl

I will assume the structure is correct since it matches histidine and will change the name to the first one I listed. Cburnett (talk) 00:22, 26 June 2011 (UTC)
