Antioxidant Chemistry of α-Tocopherol in Biological Systems

Roles of Redox Cycles and Metabolism
  • Daniel C. Liebler
Part of the Subcellular Biochemistry book series (SCBI, volume 30)


Vitamin E is the family name given to a group of tocopherols and tocotrienols that function as the principal lipid-soluble chain-breaking antioxidants in biological membranes and lipoproteins. α-Tocopherol (1) and, to a lesser extent, λ-tocopherol (2) constitute an essential component of cellular defense against endogenous and exogenous oxidants.
