New experimental data on the fragmentation of the tyrosine amino acid molecule ( are presented being related to the formation of the ionized products due to the low-energy electron impact. The resulting fragments have been identified and analyzed using an extensive DFT theory approach. The results allowed the main pathways of the electron-impact tyrosine molecule fragmentation to be suggested. The absolute appearance energies for several fragments have been measured experimentally and calculated theoretically, compared and analyzed.
