title: Tocopherol distribution in serum lipoproteins with respect to red blood cell tocopherol levels in children.
abstract: The relation of lipoprotein tocopherol levels to red blood cell (RBC) tocopherol was investigated in 81 healthy children, comprising 44 males and 37 females, using a new technique for separation of individual lipoprotein fractions. 1. In children there were no age and sex differences in tocopherol contents among individual lipoprotein fractions. The tocopherol content of high density lipoprotein (HDL) was slightly higher than that of low density lipoprotein (LDL), but this difference was not statistically significant. 2. The tocopherol content of HDL fractions was closely correlated with RBC tocopherol concentration, but there was no relationship in tocopherol levels between RBC and LDL and between RBC and very low density lipoprotein (VLDL). 3. There were no age and sex differences in contents of total cholesterol (T-ch), triglycerides (TG), phospholipids (PL), total lipids, HDL-cholesterol, LDL or VLDL in children.
