| In vitro study | γ-Tocopherol (D-γ-Tocopherol) is well absorbed and accumulates to a significant degree in some human tissues; it is metabolized, however, largely to 2,7,8-trimethyl-2-(beta-carboxyethyl)-6-hydroxychroman (gamma-CEHC), which is mainly excreted in the urine. Plasma concentrations of γ-Tocopherol (D-γ-Tocopherol) are inversely associated with the incidence of cardiovascular disease and prostate cancer. |

[2R[2R*(4R*,8R*)]]-3,4-dihydro-2,7,8-trimethyl-2-(4,8,12-trimethyltridecyl)-2H-benzopyran-6-ol - Introduction
Tocopherol (vitamin E)(TCP) is a series of (α,β,γ and δ) chiral organic molecules. The difference of these chiral molecules is through their benzodihydropyranol group The degree of methylation comes from the change. Vitamin E is a fat-soluble antioxidant that protects cell membranes from oxidative damage. Alpha-tocopherol is a form that modern people preferentially absorb. Alpha-tocopherols of different subtypes and analogs have opposite and differentiated regulatory activities in vivo.

| EPA chemical information | Information provided by: ofmpub.epa.gov (external link) |
| Tocopherol derivatives | Tocopherol mainly has four derivatives, which are divided into four types: α, β, γ and δ according to the methyl position. The activity of tocopherol-related compounds tocotrienol is certain when the substituents are different, but the activity of tocopherol will be significantly reduced. The following is the simplified structure of the two: The following table lists the activity ratio of tocotrienol to tocopherol after substitution with the following functional groups: |
| Biological activity | γ-Tocopherol (D-γ-Tocopherol) is an effective cyclooxygenase (cyclooxygenase) inhibitor. γ-Tocopherol is a natural form of vitamin E found in many plant seeds, such as corn oil and soybean. γ-Tocopherol has anti-inflammatory properties and anti-cancer activity. |
