Urinary excretion of pyruvic acid, alpha-ketoglutaric acid and oxaloacetic acid in scurvy.
Scurvy is associated with abnormal carbohydrate metabolism and diminished production of insulin (1). Banerjee et al. (2) observed increased accumulation of citrate, malate, and lactate in the tissues of scorbutic guinea pigs. This was possibly due to the insulin insufficiency associated with scurvy since prolonged injection of insulin to scorbutic guinea pigs diminished the tissue concentration...
متن کاملCclxv. Reactions of Pyruvic Acid with Thiolacetic Acid and Cysteine. by Ernst Friedmann and Joseph
BAUMANN [1885,2] observed that the action of ethyl-, phenyland p-bromophenylmercaptans on pyruvic acid led to the exothermic formation of substances which could be recrystallized from benzene and possesMed well-defined melting-points. Though stable in the solid state and in benzene solution, these compounds were rapidly broken down to their original constituents when dissolved in water, and wer...
متن کاملDegradation of Lactic Acid and Pyruvic Acid in Belousov-Zhabotinskii Reactions
The temporal degradation of the Belousov-Zhabotinskii substrates lactic acid, pyruvic acid, bromoand dibromo pyruvic acid is investigated. The only final product of non-brominated substrates is acetic acid. From brominated educts only brominated acetic acids result. The con centrations of the stable products are determined as a function of time. The gross reactions are mainly based on simple c...
متن کاملGlyoxylic acid oxidation by rat liver.
The enzymatic formation of glyoxylate from tricarboxylic acids has focused attention on this cu-keto acid as a possible intermediate of alternate metabolic pathways (l-3). Although the isocitritase reaction has not been shown in animal tissues, recent work has indicated that the principal degradative pathway for glycine by rat liver preparations proceeds via glyoxylic acid (4). Although the oxi...
متن کاملPhotochemistry of aqueous pyruvic acid.
The study of organic chemistry in atmospheric aerosols and cloud formation is of interest in predictions of air quality and climate change. It is now known that aqueous phase chemistry is important in the formation of secondary organic aerosols. Here, the photoreactivity of pyruvic acid (PA; CH3COCOOH) is investigated in aqueous environments characteristic of atmospheric aerosols. PA is current...
