Lipid-peroxyl-radical scavenger in cell membranes — donates H· from the chromanol hydroxyl to terminate lipid peroxidation chain reactions. Regenerated to active form by ascorbate and glutathione. α-Tocopherol is preferentially retained by hepatic α-TTP; other isoforms (γ, δ, tocotrienols) are largely excreted.
