At the same time, increases in the selenium content of plant organs, be it due to the use of selenium-containing fertilizers or biofortification technologies, must not be excessively high, because high doses of this element is toxic to plants (30 mg/kg DMB or above), animals, and humans (5 mg/day) (Finley, 2005; Kabata-Pendias, 2010).
4.2.1 Structure. It is generally believed that selenium–protein complex is the main existing state and function form of selenium in the body. There are two kinds of structure existence forms of selenium in protein. One is a non-covalent bond form and the other is a covalent bond form.
In the second synthesis route for preparing the selenium-containing isoxazolamines represented by general formula I-a, I-b, I-c, I-d, and I-ef, the different substituted 2,2′-diselenylbisbenzaldehydes can respectively react with different 3-amino-2,6-piperidinedione or 3-amino-1,4-dihydropyridine-2-(1H)-one or 3-amino-1-adamantanol or 2 ...
For example, using glucose-supported selenium containing 33 mg of Se for each 100 m 2 area could enhance the selenium content in rice to over the requirement of GB/T 22499-2008 (i.e., 40 μg/kg). Notably, unlike other foliar fertilizers, the use of carbohydrate-supported selenium does not require any surfactant because the hydroxyl …
Beyond the use of classic or novel selenium containing molecules in the form of supplements, biofortification of fruits, vegetables and crops with selenium may also represent a valuable strategy to ensure the general population an adequate selenium intake according to global or local guidelines. Selenium concentration in foodstuffs …
Selenium side effects. Get emergency medical help if you have any of these signs of an allergic reaction: hives; difficult breathing; swelling of your face, lips, tongue, or throat. Long term use of high selenium doses can lead to dangerous side effects. Stop taking selenium and call your doctor at once if you have: nausea, vomiting;
