Pyruvic Acid Content in Human Milk with Different Arakawa's Reaction

Characterization of Xanthan Products of Differing Pyruvic Acid Content

“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...

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...

Reverse reaction of malic enzyme for HCO3- fixation into pyruvic acid to synthesize L-malic acid with enzymatic coenzyme regeneration.

Malic enzyme [L-malate: NAD(P)(+) oxidoreductase (EC 1.1.1.39)] catalyzes the oxidative decarboxylation of L-malic acid to produce pyruvic acid using the oxidized form of NAD(P) (NAD(P)(+)). We used a reverse reaction of the malic enzyme of Pseudomonas diminuta IFO 13182 for HCO(3)(-) fixation into pyruvic acid to produce L-malic acid with coenzyme (NADH) generation. Glucose-6-phosphate dehydro...

Protein Content of Human Milk, from Colostrum to Mature Milk

By definition, mammals are those animals that suckle their young and they comprise the highest class of vertebrates. Thus lactation is one important distinguishing characteristic of this class of animals. Mammals are born at markedly different stages of maturity and if it is assumed that their nutritive requirements correspond to their physiological maturity, one may reason Ideologically that t...
