Histidine |
|
| The chemical structure of Histidine is shown at the right. The absorption and fluorescence emission spectra are shown below. The structure, absorption, and fluorescence data were all obtained from the PhotochemCAD package by Jonathan Lindsey. This excellent program allows rapid comparison of spectra and enables one to do a variety of photochemically relevant calculations. |

Absorption
This is a graph of the molar extinction coefficient of Histidine dissolved in water. It was measured by Junzhong Li on 12/11/97 [H. Du, R. A. Fuh, J. Li, A. Corkan, J. S. Lindsey, "PhotochemCAD: A computer-aided design and research tool in photochemistry," Photochemistry and Photobiology, 68, 141-142, 1998]. Histidine has a molar extinction coefficient of 5,700 M-1cm-1 at 211 nm [G. D. Fasman, Handbook of Biochemistry and Molecular Biology, Proteins, I, 183-203, CRC Press, 3 ed., 1976]. No fluorescence was observed, thus no file is included. |
