1 In this work, the effect of Fenton reaction on two elastin cross-linked amino acids, desmosine (DES) and isodesmosine (IDE), in the absence or presence of different wavelength radiations generated from artificial sources has been evaluated using LC/ESI-MS. Irradiation as well as incubation of DES or IDE solutions in the presence of Fe(2+) and H(2)O(2) resulted in products with m/z 497.1 and 481.1 for [M+H](+). Iron elastin Homo sapiens
