摘要

In this theoretical—experimental approach, we show using ab initio calculations behavior consistent with the activation of 7-dehydrocholesterol, provitamin D_3, as an initial reactant toward ultraviolet-activated reactions of vitamin D_3. We find using molecular orbital theory that a conformation between the provitamin and the vitamin shows higher conductance than those of the reactant and product. We also find experimental evidence of this electrical character by directly measuring current—voltage characteristics on irradiated and nonirradiated samples of the provitamin. The activation of the provitamin D_3 is characterized with an increase in current during the irradiation.
