Thekey difference between tocopherols and tocotrienolsis that tocopherols have saturated isoprenoid side chains, whereas tocotrienols have unsaturated isoprenoid side chains.
There are different forms of vitamin E. They can occur mainly as tocopherols or tocotrienols. These are very important biological compounds that play important roles in biochemical processes that take place in the human body.

什么是生育酚?
Tocopherol is a type of organic compound that comes under the group of methylatedphenols。许多甲基酚类维生素E交流tivity. This vitamin activity has led to its name as well. When considering the source of tocopherols, specifically alpha-tocopherols, supplements and European food, which is rich in olive and sunflower oil, are the major sources. However, we can find gamma-tocopherols commonly in American food, where soybean and corn oil intake is comparatively very high.
More precisely, vitamin E can occur in eight different ways: four tocopherols and four tocotrienols. All these compounds have a chromane ring structure with a hydroxyl group that tends to donate a hydrogen atom to reduce the自由基content and ahydrophobicside chain that can allow the penetration into the biological membranes.
Typically, alpha-tocopehrol can be found as the most preferentially absorbed vitamin E in humans. This compound has three stereocenters, which makes it a chiral compound. These stereocenters are responsible for the difference between the arrangement of groups around the stereocenter to give different tocopherol forms. Nevertheless, tocopherols are important as radical scavengers that can quench free radicals.
什么是生三烯醇?
Tocotrienols are a group of organic compounds and a type of vitamin E. There are four major structures of this compound known as the alpha, beta, gamma, and delta forms. Typically, tocotrienols have unsaturated isoprenoid side chains consisting of three carbon-carbon double bonds.
We can find this type of vitamin E mainly in vegetable oils such as palm oil, rice bran oil, wheat gram, barley, saw palmetto, annatto, some grains, nuts, and their oils. Although the different vitamin E forms show some activity as chemical antioxidants, all of these structures do not have the same vitamin E equivalency. Typically, tocotrienols show activity depending on the type of antioxidant performance that is being measured.
生育酚和生育三烯醇之间有什么相似之处?
- Tocopherols and tocotrienols are methylated phenols.
- 生育酚和生育三烯醇都具有维生素E活性。
- They are fat-insoluble antioxidants.
生育酚和生育三烯酚有什么区别?
There are different forms of vitamin E that can occur mainly as tocopherols or tocotrienols. These are very important biological compounds that play important roles in biochemical processes that take place in the human body. The key difference between tocopherols and tocotrienols is that tocopherols have saturated isoprenoid side chains, whereas tocotrienols have unsaturated isoprenoid side chains.

Summary – Tocopherols vs Tocotrienols
我们可以找到可能主要作为生育酚或生育三烯醇的不同形式的维生素E。生育酚是甲基化苯酚群下的有机化合物。生育三烯醇是一组有机化合物,是一种维生素E。生育酚和生育三烯酚之间的关键差异是,生育酚具有饱和的异丙型侧链,而舒适醇具有不饱和的异丙核侧链。
