Biological Activity

[Description]:

(rel)-β-Tocopherol is a relative configuration of β-Tocopherol.(±)-β-Tocopherol is a lipid-soluble form of vitamin E with antioxidant activity. β-Tocopherol can inhibit tyrosinase activity and melanin synthesis. β-Tocopherol also can prevent the inhibition of cell growth and of PKC activity caused by d-alpha-tocopherol[1].
