From Fat To Bilayers: Understanding Where And How Vitamin E Works, Jeffrey Atkinson, Drew Marquardt, Mitchell Dipasquale, Thad Harroun

Chemistry and Biochemistry Publications

Vitamin E was one of the last fat-soluble vitamins to be discovered. We provide here an historical review of the discovery and the increasingly more detailed understanding of the role of α-tocopherol both as an antioxidant and as a structural component of phospholipid bilayer membranes. Despite the detailed descriptions now available of the orientation, location, and dynamics of α-tocopherol in lipid bilayers, there are still gaps in our knowledge of the effect of α-tocopherol and its potential receptors than control gene transcription.
