Pyruvate oxidation in pigeon brain catalyzed by fumarate

The accumulation of citrate during oxidation of pyruvate by breis and slices of pigeon brain.

Highly Selective Oxidation of Ethyl Lactate to Ethyl Pyruvate Catalyzed by Mesoporous Vanadia–Titania

The direct oxidative dehydrogenation of lactates with molecular oxygen is a "greener" alternative for producing pyruvates. Here we report a one-pot synthesis of mesoporous vanadia-titania (VTN), acting as highly efficient and recyclable catalysts for the conversion of ethyl lactate to ethyl pyruvate. These VTN materials feature high surface areas, large pore volumes, and high densities of isola...

The effect of insulin upon pyruvate utilization by pigeon muscle.

The recent demonstration by Cori (1) that the hexokinase reaction is controlled by the interaction of insulin, anterior pituitary, and adrenal cortical hormones naturally raises the question as to whether the chemical action of insulin can be totally explained on the basis of this’one effect. The evidence indicating that insulin is concerned more directly with oxidative reactions in the carbohy...

Pyruvate oxidation in Desulphovibrio desulphuricans.

The metabolism of Desulphovibrio desulphuricans does not appear to have been studied extensively. Stephenson and Stickland (1931) and Sisler and ZoBell (1950) showed that the organism can use gaseous hydrogen as a reducing agent for sulfate reduction. By growing cultures for several generations in mineral salt solution containing less than one part per million of sulfate, Sisler and ZoBell (195...

Unsaturated lipide oxidation catalyzed by hematin compounds.

Hematin catalysis of unsaturated lipide oxidation is probably a primary reaction in many types of pathological unsaturated fat oxidation in viva (l-3) and in the spoilage of frozen meat products by oxidative fat rancidity (4). Some of the properties of hematin catalysis have been described (4-8), but knowledge of the reaction mechanism and the reaction products is relatively meager. The catalyt...
