“…In addition, it seems that sulphur in the glucosinolate structure may be replaced by similar selenium under selenoglucosinolates formation. However, these compounds are still discussed (Bertelsen et al 1988). Glucosinolates are derived from a limited group of amino acids, including alanine, leucine, methionine, phenylalanine and tryptophan.…”

The mustard family -Brassicaceae -is well known as family of plants, metallophytes, which are able to accumulate wide range of heavy metals and metalloids, especially zinc and cadmium, but also nickel, thallium, chromium and selenium. Ecological importance of this process consists partially in plants themselves to survive negative environmental conditions. There are two basic different strategies, how to survive these conditions -accumulation of heavy metals in plants tissues with different intensity in individual cell types, but also organs, which is partially given by chemical composition of cell walls, and ability to synthesize special defensive -detoxification compounds rich on thiol groupsglutathione and phytochelatins, which are able to bind heavy metals and transport them to the "secure" cell compartment -vacuole. The second principle is based on ability to exclude heavy metals. Role of secondary metabolites rich on sulphur in detoxification of heavy metals is still discussed with unclear conclusions. Members of Brassicaceae family, especially genera Thlaspi and Brassica, are well-known hyperaccumulators of heavy metals with possible utilization in phytoremediation technologies. In this review chapter, mechanisms of cadmium uptake and transport and its deposition in various plant cells and tissues are discussed with respect with

Selenium appears in the natural selenium cycle in the form of several organic and inorganic compounds. The biologically beneficial and detrimental effects of 'selenium' must be ascribed to particular selenium compounds. The identification and quantification of selenium compounds in biological and environmental samples is required for an understanding of the role of selenium. The highperformance liquid-chromatographic (HPLC) methods for the separation, identification and quantification of selenite, selenate, hydrogen selenide, methaneselenol, bis(organothi0) selenides, trimethylselenonium salts, selenoamino-acids, selenium derivatives of carbohydrates, selenoproteins, selenonucleosides and other miscellaneous selenium compounds are summarized (193 references) and pertinent detection modes discussed. Advantages and disadvantages of the methods are pointed out. The literature is covered since 1974, the year of the first publication in this field.

“…Several inorganic and organic compounds were identified in biological samples (animals, plants, and microorganisms). Among these compounds are selenite, selenate, dimethyl selenide, trimethylselenonium salts, selenium derivatives of carbohydrates 4, selenoamino acids, selenium‐containing proteins (enzymes) 5,6, and selenium‐containing nucleosides 7. Selenium compounds have been found capable of inhibiting and/or retarding tumorigenesis in a variety of experimental animal models 8,9.…”

A theoretical study of 2-Se-(2-methyl-2-propenyl)-1-benzoic acid was carried out to investigate the molecular and electronic structure of this molecule, using the B3LYP density functional theory (DFT) method with the 6-311ϩG** basis set. The optimized geometry of the molecule was obtained for the ortho, meta, and para isomers of the complex. In addition, the theoretical vibrational spectrum is presented, and thermal corrections in the limit of 100 -1,000 K are discussed using the Shomate thermodynamic equations.
