Abstract
Táto bakalárska práca sa zameriava na prípravu a charakterizáciu komplexov železa s aminokyselinami. Práca je v teoretickej časti sústredená na rozobratie železa ako esenciálneho prvku v organizmoch, na jeho schopnosť tvoriť komplexy a na rozmanité biologické vlastnosti týchto komplexov, ktoré môžu byť prirodzené až vedúce k rôznym poruchám ich metabolizmu. Preštudovaná literatúra v práci sa orientuje na prípravu komplexov Fe(III) s aminokyselinami. V experimentálnej časti práce sa venujeme titračným stanovenia zeta potenciálu a kritickej agregačnej koncentrácii, ktorá bola stanovená len pri aminokyselinách L-lyzín a kyseline asparágovej. Taktiež sa venujeme zrážacím reakciám, ktoré mali malú výťažnosť vo väčšine zvolených aminokyselinách okrem cysteínu, ktorého množstvo bolo po úprave podmienok dokonca dvojnásobné. Konštatovali sme, že výsledný výťažok závisí hlavne od druhu použitej aminokyseliny, tak isto aj od použitého rozpúšťadla a aj jeho množstva využitého v syntéze.
This bachelor thesis focuses on the preparation and characterization of iron complexes with amino acids. The work in the theoretical part is focused on specification of iron as an essential element in living organisms, on his abilities to build complexes and on its wide range of biological attributes of these complexes, which can be natural or leading to various disorders of their metabolism. The studied literature is oriented on preparation of Fe(III) complexes with amino acids. In the experimental part of work we deal with titrational setting of zeta potential and critical aggregation concentration which were set only for amino acids L-lysine and an Aspartic acid. We also deal with coagulation reactions that had low yield in most of the selected amino acids except cystein, which doubled its amount after the modification of the conditions. We have stated that the resulting yield depends mainly on the type of used amino acid as well as on the used solvent and its amount used in synthesis.
