描述信息

2,5,7,8-tetramethyl-2-(4,8,12-trimethyltridecyl)-3,4-dihydro-2H-1-benzopyran-6-ol is a tocopherol.
Tocopherol exists in four different forms designated as α, β, δ, and γ. They present strong antioxidant activities, and it is determined as the major form of vitamin E. Tocopherol, as a group, is composed of soluble phenolic compounds that consist of a chromanol ring and a 16-carbon phytyl chain. The classification of the tocopherol molecules is designated depending on the number and position of the methyl substituent in the chromanol ring. The different types of tocopherol can be presented trimethylated, dimethylated or methylated in the positions 5-, 7- and 8-. When the carbons at position 5- and 7- are not methylated, they can function as electrophilic centers that can trap reactive oxygen and nitrogen species. Tocopherols can be found in the diet as part of vegetable oil such as corn, soybean, sesame, and cottonseed. It is currently under the list of substances generally recognized as safe (GRAS) in the FDA for the use of human consumption.
DL-alpha-Tocopherol is a natural product found in Sida acuta, Tainia latifolia, and other organisms with data available.
dl-alpha-Tocopherol is a synthetic form of vitamin E, a fat-soluble vitamin with potent antioxidant properties. Considered essential for the stabilization of biological membranes (especially those with high amounts of polyunsaturated fatty acids), d-alpha-Tocopherol is a potent peroxyl radical scavenger and inhibits noncompetitively cyclooxygenase activity in many tissues, resulting in a decrease in prostaglandin production. Vitamin E also inhibits angiogenesis and tumor dormancy through suppressing vascular endothelial growth factor (VEGF) gene transcription. (NCI04)
