Photochemistry 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 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...
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 کاملThe Utilization of Pyruvic Acid by Bakers’ Yeast*
If sodium pyruvate is added to cells of bakers’ yeast suspended in a phosphate buffer of pH 7.0 in the strict absence of oxygen, practically no pyruvate is utilized. After 3 hours in contact with the cells the sodium pyruvate can be almost quantitatively recovered. If, however, oxygen is admiNed to the cells, then both pyruvate and oxygen are utilized at appreciable rates (see Table I). So far ...
متن کاملRecent Progress in the Microbial Production of Pyruvic Acid
Pyruvic acid (pyruvate) is a cellular metabolite found at the biochemical junction of glycolysis and the tricarboxylic acid cycle. Pyruvate is used in food, cosmetics, pharmaceutical and agricultural applications. Microbial production of pyruvate from either yeast or bacteria relies on restricting the natural catabolism of pyruvate, while also limiting the accumulation of the numerous potential...
