Özet
Powders of L-lysine monohydrochloride and L-glutamic acid hydrochloride were gamma irradiated and the induced free radicals were investigated at room temperature by electron magnetic resonance techniques. The observed species in these compounds were attributed to the H(2)NCH(2)CH(2)CH(2)CH(2)CHGOOH and HOOCCH2CH2CHCOOH radicals, respectively. In both radicals, the unpaired electron interacted with alpha-proton and beta-protons. Also, the FT-IR and thermal analyses of both compounds were investigated. The functional groups in the molecular structures of L-lysine monohydrochloride and L-glutamic acid hydrochloride were identified by FT-IR spectrometer. The TGA, DTA and DTG graphics were obtained to explain the thermal behavior of molecules. (C) 2011 Elsevier B.V. All rights reserved.
