Regulation of Gluconeogenesis documents the proceedings of 9th Conference of the Gesellschaft für Biologische Chemie. This meeting was first planned as a continuation of a former Conference of the Gesellschaft für Biologische Chemie on ""Stoffwechsel der isoliert perfundierten Leber"". However, the organizers of the present meeting decided that it seemed far more reasonable to restrict the subject to a special biochemical problem than to a technical procedure which had not changed very much during the last years. This volume contains 24 chapters and begins with a paper that identifies the substrates, activators, and inhibitors which may influence the rate of reaction of pyruvate carboxylase from liver. Other papers deal with topics such as purification and properties of pyruvate carboxylase from rat liver; the location of pyruvate carboxylase in mitochondria; effects of quinolinic acid on the free and total nicotinamide-adenine dinucleotides of rat liver; and effects of biguanides on gluconeogenesis in rats and guinea pigs.
