Background. L-selenocystein (oxidized form of selenocystine) – the 21st proteinogenic aminoacid, the most significant natural selenium compound and a promising substance for correction of human selenium deficiency. An important stage of operations with l-selenocystine is the development of analytical methods of l-selenocystine identification and quantitative determination.
Materials and methods. TLC, capillary electrophoresis (Kapel 105 M) were used for detection of l-selenocystine. An elemental analysis was carried out on a vatio El cube Elementar Analysensysteme (Germany). NMR1H and 13C spectra were obtained on a Varian 400 spectrophotometer with operating frequencies of 400 and 100 MHz accordingly.
Results. The purity of l-selenocystine was evaluated using thin layer chromatography (TLC) and capillary electrophoresis. The structure of l-selenocystine was proved via the elemental analysis and 1H and 13C NMR methods.
Conclusions. As a result of the research carried out there have been developed analytical methods of l-selenocystine determination using TLC and capillary electrophoresis. The chemical structure of l-selenocystibe has proved via the elemental analysis and 1Н, 13С NMR spectrometry.
