[2R[2R*(4R*,8R*)]]-3,4-dihydro-2,5,8-trimethyl-2-(4,8,12-trimethyltridecyl)-2H-benzopyran-6-ol Chemical Properties,Usage,Production

Chemical Properties

Brownish Yellow Oil

Uses

One of the naturally occurring forms of Vitamin E. Is biologically less active than α-Tocopherol.

Definition

ChEBI: Beta-tocopherol is a tocopherol in which the chroman-6-ol core is substituted by methyl groups at positions 5 and 8. While it is found in low concentrations in many vegetable oils, only cottonseed oil contains significant amounts. It has a role as a plant metabolite and a food component. It is a vitamin E and a tocopherol.
