for experimental asthma in mice and for asthma in Europeans who consume diets low gT but not for Americans who consume diets high in gT, suggesting that differences in the outcomes in these reports on vitamin E may, in part, reflect the opposing effects of 伪-tocopoherol and 纬-tocopherol...
Natural forms of vitamin E and 130-carboxychromanol, a long-chain vitamin E metabolite, inhibit leukotriene generation from stimulated neutrophils by blocking calcium influx and suppressing 5-lipoxygenase activity, respectively. J Immunol 2011;186:1173e9. Jin X, Shah S, Liu YN, Zhang HR, Lees M...
aSerum concentrations of vitamin E (alpha-tocopherol) depend on the liver, which takes up the nutrient after the various forms are absorbed from the small intestine. The liver preferentially resecretes only alpha-tocopherol via the hepatic alpha-tocopherol transfer protein [1]; the liver metabolize...
Ultraviolet radiation B stimulates both the production of vitamin D 3 in the skin and the activation of the skin analog of the hypothalamic-pituitary-adrenal axis (HPA) as well as the central HPA. Since the role of vitamin D 3 in the regulation of the HPA is largely unknown, we investigat...
This chapter discusses the determination of various forms of vitamin E in tissues and diets by high-performance liquid chromatography (HPLC) using normal-phase diol column. Vitamin E is a generic term that includes a mixture of tocopherols (T) and tocotrienols (T3) that differs in the number ...
Tocopherol form affects vitamin E: three studies have been conducted to assess the effects of different forms of vitamin E on vitamin E status. Results from these studies indicate that the source of vitamin E significantly affects vitamin E status in exercised and unexercised horses.(research of ...

The contents of six vitamin B6 forms, pyridoxine-β-glucoside, and 4-pyridoxic acid in mature milk of 20 Japanese lactating women consuming ordinary Japanese foods were determined by a 4-pyridoxolactone-conversion HPLC method. These compounds were determined with the average recovery rate of 83.9%...
these two compounds is the functionality of each in vivo, particularly given the fact that the natural form ofvitamin E is a single chemical structure and the synthetic compound is .a mixture of eight. The results of investigations into the differences in natural and synthetic vitamin E will ...
