In this scheme, the racemase involves a rearrangement of the hydrogen about the asymmetrical carbon (6,7), while the mutase reaction involves an intramolecular migration (8, 9) of the thioester group (l&12). Two approaches are available to determine the source of the hydrogen that arises on carbon 3 of succinyl-CoA as a result of methylmalonyl-Coil mutase action. The first or indirect approach,...

INTRODUCTION Since, in future fusion reactors, the activity of tritium handled as the fuel is enormously large, i.e., about 10 TBq per a fusion reactor power of 1000 MW, it is necessary to develop more excellent handling technique of tritium and to store the research results related to the fusion reactor technology. In particular, it is expected that researchers and workers of the fusion reacto...

The influence of low temperature in the root zone on water uptake in lodgepole pine (Pinus contorta Dougl. ex Loud.) was studied under laboratory conditions. To remove soil hydraulic influences, two-year-old seedlings were transferred to solution cultures and maintained in temperature controlled water baths. Short term measurements of leaf conductance, leaf water potential and tritiated water m...
