alpha-Tocopherol

Alpha-tocopherol is a pale yellow, viscous liquid. (NTP, 1992) (R,R,R)-alpha-tocopherol is an alpha-tocopherol that has R,R,R configuration. The naturally occurring stereoisomer of alpha-tocopherol, it is found particularly in sunflower and olive oils. It has a role as an antioxidant, a nutraceutical, an antiatherogenic agent, an EC 2.7.11.13 (protein kinase C) inhibitor, an anticoagulant, an immunomodulator, an antiviral agent, a micronutrient, an algal metabolite and a plant metabolite. It is an enantiomer of a (S,S,S)-alpha-tocopherol. In 1922, vitamin E was demonstrated to be an essential nutrient. Vitamin E is a term used to describe 8 different fat soluble tocopherols and tocotrienols, alpha-tocopherol being the most biologically active. Vitamin E acts as an antioxidant, protecting cell membranes from oxidative damage. The antioxidant effects are currently being researched for use in the treatment of diseases causing bone loss, cardiovascular diseases, diabetes mellitus and associated comorbidities, eye diseases, inflammatory diseases (including skin conditions), lipid disorders, neurological diseases, and radiation damage. Though this research is so far inconclusive, vitamin E remains a popular supplement and is generally considered safe by the FDA. Vitamin E is a natural product found in Monteverdia ilicifolia, Calea jamaicensis, and other organisms with data available. Alpha-Tocopherol is the orally bioavailable alpha form of the naturally-occurring fat-soluble vitamin E, with potent antioxidant and cytoprotective activities. Upon administration, alpha-tocopherol neutralizes free radicals, thereby protecting tissues and organs from oxidative damage. Alpha-tocopherol gets incorporated into biological membranes, prevents protein oxidation and inhibits lipid peroxidation, thereby maintaining cell membrane integrity and protecting the cell against damage. In addition, alpha-tocopherol inhibits the activity of protein kinase C (PKC) and PKC-mediated pathways. Alpha-tocopherol also modulates the expression of various genes, plays a key role in neurological function, inhibits platelet aggregation and enhances vasodilation. Compared with other forms of tocopherol, alpha-tocopherol is the most biologically active form and is the form that is preferentially absorbed and retained in the body. A generic descriptor for all tocopherols and tocotrienols that exhibit alpha-tocopherol activity. By virtue of the phenolic hydrogen on the 2H-1-benzopyran-6-ol nucleus, these compounds exhibit varying degree of antioxidant activity, depending on the site and number of methyl groups and the type of isoprenoids.

View More ... alpha-Tocopherol is traditionally recognized as the most active form of vitamin E in humans and is a powerful biological antioxidant. The measurement of "vitamin E" activity in international units (IU) was based on fertility enhancement by the prevention of spontaneous abortions in pregnant rats relative to alpha-Tocopherol. Natural vitamin E exists in eight different forms or isomers: four tocopherols and four tocotrienols. In foods, the most abundant sources of vitamin E are vegetable oils such as palm oil, sunflower, corn, soybean, and olive oil. Nuts, sunflower seeds, and wheat germ are also good sources. Constituent of many vegetable oils such as soya and sunflower oils. Dietary supplement and nutrient. Nutriceutical with anticancer and antioxidant props. Added to fats and oils to prevent rancidity. The naturally-occurring tocopherol is a single stereoisomer; synthetic forms are a mixture of all eight possible isomers An alpha-tocopherol that has R,R,R configuration. The naturally occurring stereoisomer of alpha-tocopherol, it is found particularly in sunflower and olive oils. α-Tocopherol (alpha-tocopherol) is a type of vitamin E. Its E number is "E307". Vitamin E exists in eight different forms, four tocopherols and four tocotrienols. All feature a chromane ring, with a hydroxyl group that can donate a hydrogen atom to reduce free radicals and a hydrophobic side chain which allows for penetration into biological membranes. Compared to the others, α-tocopherol is preferentially absorbed and accumulated in humans. Vitamin E is found in a variety of tissues, being lipid-soluble, and taken up by the body in a wide variety of ways. The most prevalent form, α-tocopherol, is involved in molecular, cellular, biochemical processes closely related to overall lipoprotein and lipid homeostasis. Ongoing research is believed to be "critical for manipulation of vitamin E homeostasis in a variety of oxidative stress-related disease conditions in humans."[2] One of these disease conditions is the α-tocopherol role in the use by malaria parasites to protect themselves from the highly oxidative environment in erythrocytes.[3] DL-α-Tocopherol.

α-tocopherol is a member of the class of compounds known as tocopherols. Tocopherols are vitamin E derivatives containing a saturated trimethyltridecyl chain attached to the carbon C6 atom of a benzopyran ring system. The differ from tocotrienols that contain an unsaturated trimethyltrideca-3,7,11-trien-1-yl chain. α-tocopherol is practically insoluble (in water) and a very weakly acidic compound (based on its pKa). α-tocopherol can be found in a number of food items such as lime, rowanberry, horseradish tree, and pineappple sage, which makes α-tocopherol a potential biomarker for the consumption of these food products. α-tocopherol is a form of vitamin E that is preferentially absorbed and accumulated in humans. The measurement of "vitamin E" activity in international units (IU) was based on fertility enhancement by the prevention of spontaneous abortions in pregnant rats relative to α-tocopherol .

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.
