Phylloquinone is converted into menaquinone-4 and accumulates in extrahepatic tissues. Neither the route nor the function of the conversion is known. One possible metabolic route might be the release of menadione from phylloquinone by catabolic activity. In the present study we explored the presence of menadione in urine and the effect of vitamin K intake on its excretion. Menadione in urine wa...
In this communication we report a p-sulfonatocalix[4]arene coated ZnS quantum dots "cup type" highly stable optical probe for the detection and determination of menadione (VK(3)) with high sensitivity and selectivity. The detection of VK(3) depends on supramolecular host-guest chemistry.
In this paper, we consider the metric packing problem for the commodity graph of disjoint two triangles K3 +K3, which is dual to the multiflow feasibility problem for the commodity graph K3 + K3. We prove Karzanov’s conjecture concerning quarter-integral packings by certain bipartite metrics.
