disodium dihydrogen phosphate [2R[2R*(4R*,8R*)]]-3,4-dihydro-2,5,7,8-tetramethyl-2-(4,8,12-trimethyltridecyl)-2H-benzopyran-6-olate

α-Tocopherol phosphate (TocP) is used along the α-tocopherol acetate, α-tocopherol-nicotinate, α-tocopherol succinate and other esterified forms as a vitamin E supplement with similar but differential activities. At the molecular level, TocP may act as a cofactor for enzymes, as an active lipid mediator or indirectly by altering membrane characteristics.
