ChEBI Name tocopherol
Definition A collective name for a group of closely related lipids that contain a chroman-6-ol nucleus substituted at position 2 by a methyl group and by a saturated hydrocarbon chain consisting of three isoprenoid units. They are designated as α-, β-, γ-, and δ-tocopherol depending on the number and position of additional methyl substituents on the aromatic ring. Tocopherols occur in vegetable oils and vegetable oil products, almost exclusively with R,R,R configuration. Tocotrienols differ from tocopherols only in having three double bonds in the hydrocarbon chain.

Biological Role(s): fat-soluble vitamin
Vitamins like A, D, E and K that dissolve in fats and are stored in body tissues. Unlike the water-soluble vitamins, these are stored in the body for long periods of time and generally pose a greater risk for toxicity when consumed in excess.
