Sažetak
The basic macromolecules of life are DNA, RNA, proteins and polysaccharides. Some components can exist in two enantiomeric forms, the D and L forms. In living organisms, only one enantiomer is selected: D-sugars and L-amino acids. However, there are some exceptions and some D- amino acids occur naturally. Furthermore, copper(II) complexes with amino acids serve as models for metalloproteins and transport types of copper which are involved in a wide range of important biological processes. Therefore, the dynamical behavior of copper(II) bis-complexes with selected chiral amino acid (nonpolar, polar and electrically charged) was studied by electron paramagnetic resonance (EPR) spectroscopy as the EPR is spectroscopic tool with a long history of the study of copper(II) complexes. The cis and trans isomers were confirmed by simulation of EPR spectra for both L - and D - enantiomers. The influence of chirality on rotational motion of Cu(II)-amino acids complexes was examined.
