“coupling” of Phosphorylation with Oxidation of Pyruvic Acid in Brain*
An analysis of the dialyzable components of the pyruvic acid oxidation system of brain showed that in addition to cocarboxylase (thiamine pyrophosphate) (2), a C, dicarboxylic acid (2), and magnesium or manganese ions (3), both inorganic phosphate and “adenine nucleotide” (adenylic acid, adenosine triphosphate) (4) are required. The latter observation suggested that a cycle of phosphorylation i...
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...
متن کاملPyruvic acid egg medium for tubercle bacilli.
Sputum culture for tubercle bacilli on a solid egg medium containing glycerol was compared with culture on a similar medium containing pyruvic acid and no glycerol. Tubercle bacilli from the sputum of five out of 99 patients grew on pyruvic acid medium but not on glycerol medium. The addition of pyruvic acid is therefore essential when an egg medium is used for the cultural diagnosis of tubercu...
متن کاملPhotoinduced oligomerization of aqueous pyruvic acid.
The 320 nm-band photodecarboxylation of aqueous pyruvic acid (PA), a representative of the alpha-oxocarboxylic acids widely found in the atmospheric aerosol, yields 2,3-dimethyltartaric (A) and 2-(3-oxobutan-2-yloxy)-2-hydroxypropanoic (B) acids, rather than 3-hydroxy-2-oxobutanone as previously reported. A and B are identified by liquid chromatography with UV and ESI-MS detection, complemented...
متن کاملPyruvic Acid I. Collection of Blood for the Determination of Pyruvic and Lactic Acids*
The accurate determination of pyruvic and lactic acids is a matter of considerable theoretical and practical importance. These acids play a role in the metabolism of carbohydrates, and they are found in increased concentration in the blood in conditions of thiamine deficiency. Recently we suggested (1) the determination of the ratio of lactic to pyruvic acid in the blood as a measure of oxidati...
