Changes of thiols content at plants tester with heavy metals
Original language description
Sulfur exists in multiple stable oxidation states; hence it is a versatile component in biological systems. The most active and reduced form of sulfur in biomolecules is the thiol group (-SH), present in number of biologically active compounds. Thiol compounds have a huge number of biological activities, e.g. control of gene expression, signal transduction and heavy metal detoxification. Thiols responsible for heavy metal detoxifying in plants are called phytochelatins. These small peptides consists of4-23 amino acids, participate in the detoxification of heavy metals, because they have an ability to transport heavy metal ions to vacuole, where an immediate toxicity do not menace yet. PCs have a basic formula (γ-Glu-Cys)n-Gly (n = 2 to 11). PCs are synthesized from glutathione. Reduced glutathione (GSH) itself plays the important role in cell protection against heavy metals, and reactive oxygen species that are able to oxidize GSH to GSSG (oxidized glutathione; disulfide glutathi

Změny thiolů v rostlinách vystavených účinkům těžkých kovů
Czech description
Thiolové sloučeniny slouží jako biomarkery stresových situací. Pro stanovení thiolů u rostlin vystavených účinkům těžkých kovů jsme využili vysokoúčinné kapalinové chromatografie s elektrochemickou detekcí.
