Abstract
U ovom završnom radu su ispitivana oksido-redukcijska svojstva L-histidina u pH području od pH =4 do pH = 10, te stvaranje kompleksa L-histidina sa ionima prijelaznih metala (\(Co^{2+}\),\(Mn^{2+} \) ,\(Ni^{2+} \) i \(Fe^{3+} \)) uporabom voltametrijskih metoda (cikličke i diferencijalne pulsne voltametrije) te UV/VIS spektroskopije. Utvrđeno je da je L-histidin elektroaktivan pri pH = 10, u potpuno deprotoniranom obliku te da se oksidacijski produkt L-histidina adsorbira na površinu elektrode od staklastog ugljika. Također je utvrđeno da nastaju kompleksi L-histidina i metalnog iona (\(Co^{2+}\),\(Mn^{2+} \) ,\(Ni^{2+} \) i \(Fe^{3+} \)) u omjeru 1:1 u puferu pH = 10.
Abstract (english)
In this final work, the oxido-reduction properties of L-histidine in pH range from pH=4 to pH=10 and formation of the L-histidine complex with transition metals (\(Co^{2+}\),\(Mn^{2+} \) ,\(Ni^{2+} \) i \(Fe^{3+} \)) were studied by voltammetric methods (cyclic and differential pulse voltammetry) and UV / VIS spectroscopy. It was found that L-histidine was electroactive at pH = 10, in a completely deprotonated form, and that the oxidative product of L-histidine was adsorbed on the glassy carbon electrode surface. It has also been found that complexes of L-histidine and metal ions (\(Co^{2+}\),\(Mn^{2+} \) ,\(Ni^{2+} \) i \(Fe^{3+} \)) were formed in a 1: 1 ratio in a buffer pH = 10.
