Distribution of alpha Tocopherol in Human Plasma Lipoproteins,
ARMY MEDICAL RESEARCH AND NUTRITION LAB DENVER COLO
Pagination or Media Count:
Plasma was obtained from 14 normal people after an overnight fast and the standard lipoprotein classes were separated in the ultracentrifuge. Protein, triglycerides, cholesterol, phospholipids, and alpha-tocopherol were determined on each lipoprotein and plasma sample. Alpha-tocopherol was found in all lipoprotein classes. Alpha-tocopherol level correlated best with total lipids r0.855, phospholipids r0.801, and cholesterol r0.795. Poor correlations were obtained with triglycerides r0.317 and proetin r0.368. Two subjects who were taking supplementary alpha-tocopherol were also studied and their alpha-tocopherol values were higher but distribution among lipoprotein classes was similar. Author
