Metabolite Identification
Common NameGamma-Tocopherol
DescriptionGamma-Tocopherol, also known as vitaplus e or DL-alpha-tocopherol, belongs to the class of organic compounds known as tocopherols. These 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. Gamma-Tocopherol exists as a liquid, possibly soluble (in water), and an extremely weak basic (essentially neutral) compound (based on its pKa) molecule.

Enzymes

General function:
Involved in lipid binding
Specific function:
Carrier protein. Binds to some hydrophobic molecules and promotes their transfer between the different cellular sites. Binds with high affinity to alpha-tocopherol. Also binds with a weaker affinity to other tocopherols and to tocotrienols. May have a transcriptional activatory activity via its association with alpha-tocopherol. Probably recognizes and binds some squalene structure, suggesting that it may regulate cholesterol biosynthesis by increasing the transfer of squalene to a metabolic active pool in the cell (By similarity).
