Alcohol dehydrogenases reduce ketones with the assistance of a cofactor, nicotinamide adenine dinucleotide (NADH), or Nicotinamide adenine dinucleotide phosphate (NADPH). The enzyme–cofactor complex delivers a hydride to one prochiral face of the ketone. A mechanism needs to be in place to ...
A secondary alcohol dissolved in a C.sub.12 to C.sub.20 paraffinic hydrocarbon substantially free of aromatics and of sulfur is dehydrogenated to the corresponding ketone at a temperature of 170° - 230° C. in the presence of a catalyst of the Raney nickel type containing from 0.1 to 10...
A sample of the harvested tissue was processed into alcohol insoluble residue (AIR), and used for compositional analysis.13C enrichment was confirmed by following the procedure described in35, and all tissue used in this study had a13C incorporation rate of over 90% (Supplementary Fig.1). Mono...

Of the above-described polymers, water-soluble polymers are preferable from the standpoint of the process and environmental load. Among water-soluble polymers, at least one selected from the group consisting of cellulose ether, polyvinyl alcohol and sodium alginate is preferable, and cellulose ether ...
tetrahydrofuran, dioxane, acetonitrile and chloroform to directly oxidize the above-mentioned alcohol into the corresponding ketone in high selectivity and yield using the aforementioned catalyst without causing any problems in environmental pollution, etc., at all and the above-mentioned inexpensive oxidizin...
Secondary alcohol and ketone exchange rea- - ctionActivated alumina is used as the catalyst in an exchange reaction at autogenous pressure between secondary alcohols and ketones (R1 and R may be opt. subst. alkyl or phenyl, the substs. being 1-6C alkyl, halo, amino, cyano or phenyl; or ...
Each of the resultant glass substrates was subjected to rubbing with an acetate fiber-planted cloth and washed with an isopropyl alcohol solution. On one of the thus-treated glass substrates, silicon beads (average diameter=2.0 μm) were dispersed and then, the pair of glass substrates were ...
