Talk:Aromatic amino acids
|WikiProject Chemistry||(Rated Stub-class, Low-importance)|
Why histidine usually is not included in the aromatic aminoacids group?
- Good question. No idea myself. Lehninger does not list it, but Voet does AFAIK. 188.8.131.52 (talk) 21:12, 9 February 2014 (UTC)
Colleagues, histidine should be aromatic. It obeys aromaticity rules, exhibits aromatic properties and, no surprise, is aromatic. The reason above why Lehninger did not count it as aromatic is kinda tradition - aromatic aa supposed to have a moderate absorption at 260-300 nm region. It is pretty trivial and has nothing to do with chemistry.
