Selenium enrichment of broccoli: interactions between selenium and secondary plant compounds.
Multiple components of broccoli, such as sulforaphane (Sf) and phenolic acids, may inhibit cancer. Additionally, broccoli can accumulate selenium (Se), and Se has been demonstrated to reduce the risk of cancer. Studies were conducted to determine whether enhancement of broccoli with Se would produce a plant with superior health benefits. Although increasing the concentration of Se in broccoli f...
متن کاملInteractions between selenium compounds and those of mercury or cadmium.
Two types of mechanisms are considered in this discussion of the interactions between compounds of selenium and those of cadmium or mercury: one based on a direct chemical reaction between compounds of these elements and the other based on metabolic changes induced by selenium administration and modifying the dose-effect relationship indirectly, without a reaction between selenium and the metal...
متن کاملSelenium Compounds
Selenium is a naturally occurring substance that is toxic at high concentrations but is also a nutritionally essential element. Hydrogen selenide is the most acutely toxic selenium compound. Acute (short-term) exposure to elemental selenium, hydrogen selenide, and selenium dioxide by inhalation results primarily in respiratory effects, such as irritation of the mucous membranes, pulmonary edema...
متن کاملSelenium Enrichment of Horticultural Crops.
The ability of some crops to accumulate selenium (Se) is crucial for human nutrition and health. Selenium has been identified as a cofactor of the enzyme glutathione peroxidase, which is a catalyzer in the reduction of peroxides that can damage cells and tissues, and can act as an antioxidant. Plants are the first link in the food chain, which ends with humans. Increasing the Se quantity in pla...
متن کاملInvolvement of a broccoli COQ5 methyltransferase in the production of volatile selenium compounds.
Selenium (Se) is an essential micronutrient for animals and humans but becomes toxic at high dosage. Biologically based Se volatilization, which converts Se into volatile compounds, provides an important means for cleanup of Se-polluted environments. To identify novel genes whose products are involved in Se volatilization from plants, a broccoli (Brassica oleracea var italica) cDNA encoding COQ...
