In this investigation, we studied the uptake and depletion of alpha-tocopherol and gamma-tocopherol as well as their quinone oxidation products (see Figure 2) by RAW264.
FeCl 3 ·6H 2 O (1360 mg) was dissolved in 30 ml ethanol, and 530 mg of alpha-tocopherol (or gamma-tocopherol) was dissolved in 40 ml ethanol.
Both alpha- and gamma-tocopherol are absorbed from the intestine and secreted into chylomicrons equally well [ 6 7 ] . The selective retention of alpha-tocopherol in plasma is attributed to a number of factors such as the hepatic alpha-tocopherol transfer protein (alpha-TTP), which preferentially incorporates alpha-tocopherol (over gamma-tocopherol) into very low density lipoprotein [ 8 9 10 ] . Indeed, the affinity of the different forms of vitamin E for the alpha-TTP protein appears to be a primary determinant of their plasma levels [ 8 ] . In addition, there is evidence suggesting that gamma-tocopherol is preferentially catabolized to a water-soluble form (2,7, 8-trimethyl-2-(beta-carboxyethyl)-6-hydroxychroman or gamma-CEHC) by side chain oxidation [ 11 12 ] .
Table 3shows the initial distribution of alpha-tocopherol or gamma-tocopherol and their quinone products both in the medium and in cells as well as the distribution after 6 hr of incubation in the cell system.
When macrophages were incubated with alpha-tocopherol or gamma-tocopherol individually, the macrophage level of alpha-tocopherol was just 10-20% of that of gamma-tocopherol (Figure 3A).
