Vitamin E binding proteins in human serum.

Abstract

Distribution of vitamin E in human serum lipoprotein fraction was investigated by measuring the amount of vitamin E in various protein fractions prepared by ultracentrifugation, gel filtration and electrophoresis. The larger part of the total serum vitamin E (up to 44%) was present in the .alpha.1-lipoproteins, while the .beta.-lipoproteins contained smaller concentrations (up to 26%).
