Description
Molecules having vitamin E antioxidant activity include four tocopherols (α, β, γ, δ) and four tocotrienols (α, β, γ, δ).1 One form, α-tocopherol has the highest biological activity based on fetal resorption assays.2 δ-CEHC is a major β-oxidation metabolite of δ-tocopherol.3,4 Approximately 50% of a 3H-δ-tocopherol given as an intraperitoneal dose in rat is recovered in the urine as δ-CEHC, indicating this is the major route of metabolism.4
