Selenium 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 کاملCancer chemoprevention by garlic and garlic-containing sulfur and selenium compounds.
As early as 1550 B.C., Egyptians realized the benefits of garlic as a remedy for a variety of diseases. Many epidemiological studies support the protective role of garlic and related allium foods against the development of certain human cancers. Natural garlic and garlic cultivated with selenium fertilization have been shown in laboratory animals to have protective roles in cancer prevention. C...
متن کاملPreparation and some properties of low-molecular-weight selenotrisulfide compounds and selenium-containing, high-molecular-weight, heparin-related compounds
Low-molecular-weight selenotrisulfide (SeT) compounds were prepared by the reaction of thiol compounds [monothiols: thiosalicylic acid (TSA) and diethyldithiocarbamic acid (DDC); dithiols: dimercaptosuccinic acid, dithiothreitol and dithioerythritol] and selenious acid. For TSA, a SeT compound was isolated by preparative high-performance liquid chromatography (HPLC) and the reaction molar ratio...
متن کاملSelenium compounds for fish health: An update
Oxidative stress has become an important subject for terrestrial and aquatic toxicology. The trace element selenium has been demonstrated in chemo-prevention and drug-resistance through reduction of oxidative stress. Selenium compounds could prevent damage to the unsaturated fatty acid of subcellular membranes by lipid peroxidation induced by free radicals in fish.
متن کامل(E)-Methyl 2-benzyl-3-o-tolylacrylate
In the title compound, C(18)H(18)O(2), the methyl acrylate substituent adopts an extended E conformation with all torsion angles close to 180°. The mean plane of the acrylate unit and the phenyl ring are approximately orthogonal to each other, making a dihedral angle of 81.40 (6)°. The position of the carbonyl group with respect to the olefinic double bond is typically S-trans. The crystal pack...
