Abstract
The intracellular NAD level plays a pivotal role in numerous biological processes such as rhythm, senescence, cancer and death. The study of the intracellular NAD level has been one of the “hotspots” in biomedical research. We investigated the effect of Vitamin K on intracellular NAD level in yeast by fluorescence spectrum in this paper. Plasma membrane redox system of yeast was found to be greatly promoted by the addition of Vitamin K3 or Vitamin K1. Ferricyanide reduction catalyzed by Vitamin K was accompanied by the decrease in intracellular NADH concentration and the increase in intracellular NAD level of yeast cells.
