Alpha and Gamma Tocopherols in Cerebrospinal Fluid and Serum from Older, Male, Human Subjects

Abstract

These data suggest that the processes involved in the entry of tocopherol from blood to the CSF do not discriminate between the alpha and gamma tocopherols. In contrast, alpha tocopherol is highly preferred during the packaging of plasma lipoproteins by the liver. Our data also suggest that alpha and gamma tocopherols will be available to the human brain via transport from blood.
