[Pyruvate kinase deficiency].

Nihon rinsho. Japanese journal of clinical medicine, 1973
PK deficiency is the most common and well characterized erythroenzymopathy in the Embden-Meyerhof glycolytic pathway associated with hereditary hemolytic anemia. History of discovery, clinical features, biochemical studies, as well as recent studies on molecular level were reviewed, with a stress on our own studies. As reference materials, Tables 2 and

Aspects of enantioselective heterogeneous catalysis: structure and reactivity of (S)-(-)-1-(1-naphthyl)ethylamine on Pt[111].

Journal of the American Chemical Society, 2003
The molecular orientation, spatial distribution, and thermal behavior of the powerful chiral catalyst modifier precursor (S)-naphthylethylamine adsorbed on Pt[111] have been studied by NEXAFS, XPS, STM, and temperature programmed reaction. At 300 K, both

Highly modular synthesis of C1-symmetric aminosulfoximines and their use as ligands in copper-catalyzed asymmetric Mukaiyama-aldol reactions.

Chemistry, 2005
The development of C1-symmetric aminosulfoximines, their highly modular synthesis, and their application in enantioselective copper-catalyzed Mukaiyama-type aldol reactions between pyruvates and enolsilanes is described. In this context, the influence of

Designs for a broad substrate specificity keto acid dehydrogenase.

Biochemistry, 1990
Variations have been made to the structure of the nicotinamide adenine dinucleotide (NAD) dependent L-lactate dehydrogenase from Bacillus stearothermophilus at regions of the enzyme that we believe determine specificity toward different alpha-hydroxy ...

Disorders of pyruvate metabolism

2013
Pyruvate dehydrogenase and pyruvate carboxylase deficiency are the most common disorders in pyruvate metabolism. Diagnosis is made by enzymatic and DNA analysis after basic biochemical tests in plasma, urine, and CSF. Pyruvate dehydrogenase has three main subunits, an additional E3-binding protein and two complex regulatory enzymes.

Highly enantioselective synthesis of 2,6-disubstituted and 2,2,6-trisubstituted dihydropyrones: a one-step synthesis of (R)-(+)-hepialone and its analogues.

Journal of Organic Chemistry, 2005
An efficient enantioselective approach to chiral dihydropyrones has been developed by the hetero-Diels-Alder (HDA) reactions of (E)-4-methoxy-2-trimethylsiloxy-penta-1,3-diene (diene 1) with aldehydes and pyruvates.

Transpulmonary pyruvate kinetics

American Journal of Physiology-Regulatory, Integrative and Comparative Physiology, 2011
Shuttling of intermediary metabolites, such as pyruvate, contributes to the dynamic energy and biosynthetic needs of tissues. Tracer kinetic studies offer a powerful tool to measure the metabolism of substrates like pyruvate that are simultaneously taken up from and released into the circulation by organs.

Synthesis of Polysubstituted 1,4-Dihydropyridines via Three-Component Reaction.

, 2013
The three-component reaction between dialkyl acetylenedicarboxylate (I), methyl(arylmethylidene) pyruvates (II), and primary amines (III) in a one-pot fashion proceeds likely via a domino Michael/cyclization sequence.

Nonenzymatic decarboxylation of pyruvate

Analytical Biochemistry, 1984
Triton X-100, retinol, retinoic acid, retinal, hexane, dithiothreitol, mercaptoethanol, and some other commercially available chemicals caused nonenzymatic decarboxylation of pyruvate and alpha-ketoglutarate. "Lipids" obtained from human or pigeon liver homogenates using isopropanol/hexane also had very high nonenzymatic decarboxylating activity on ...
