The changes in level of activity during the germination of wheat seedling (Triticum durum) in the dark have been investigated with 4 enzymes of glycolysis, 2 enzymes of the pentose phosphate shunt, 2 of the tricarboxylic acid cycle, 2 of amino acid metabolism and acid phosphatase. For some enzymes, which function in photosynthesis (fructose diphosphate aldolase, glyceraldehyde phosphate dehydro...

Ethanol, acetaldehyde, and acetic acid, when applied in a volatile state in air to potato tubers, led to a climacteric-like upsurge in respiration. The respiratory upsurge was markedly enhanced when the volatiles were applied in 100% O(2).Ethanol induced a decline in the level of 2-phosphoglyceric acid and phosphoenolpyruvate while leading to the accumulation of tricarboxylic acid cycle interme...

Using analytical data and the results of degradation of glucose, lactate, and glutamate produced from [Z-14C]pyruvate or lactate, we have estimated the pathways of carbon flow during active gluconeogenesis in the kidney cortex. This approach involves a steady state model and solution with the aid of a digital computer. By the isotopic method one can estimate the rates of pyruvate carboxylase, p...

The transition to lactation period in dairy cattle is characterized by metabolic challenges, negative energy balance, and adipose tissue mobilization. Metabolism of mobilized adipose tissue is part of the adaptive response to negative energy balance in dairy cattle; however, the capacity of the liver to completely oxidize nonesterified fatty acids may be limited and is reflective of oxaloacetat...

Rickettsiae are obligate intracellular parasites of eukaryotic cells that are the causative agents responsible for spotted fever and typhus. Their small genome (about 800 protein-coding genes) is highly conserved across species and has been postulated as the ancestor of the mitochondria. No genes that are required for glycolysis are found in the Rickettsia prowazekii or mitochondrial genomes, b...

The combination of 2-hydroxy-propane-1,2,3-tricarboxylic acid (H(3)hypta, also called citric acid) and 4,4'-bipyridine (4,4'-bipy) in a 1:1.5 molar ratio leads to the formation of the title mol-ecular cocrystal, 1.5C(10)H(8)N(2)·C(6)H(8)O(7). The asymmetric unit contains one and a half 4,4'-bipy units, with one lying across a centre of inversion, and one H(3)hypta mol-ecule. The significant dif...

The search for the novel metal-organic frameworks (MOFs) materials using tetra-hydro-furan-2,3,4,5-tetra-carboxylic acid (THFTCA) as a versatile multi-carboxyl ligand, lead to the synthesis and the structure determination of the title compound, [Na(H(3)THFTCA)] or [Na(C(8)H(7)O(9))](n), which was obtained by a solution reaction at room temperature. The ligand is mono-deprotonated, coordinating ...

A 74-year-old woman with type 2 diabetes mellitus developed ketoacidosis within six days of adding metformin to imeglimin treatment. The patient was insulin-sensitive and showed preserved insulin secretion; therefore, insufficiency alone unlikely contribute the development ketoacidosis. Both partially inhibit complex I in mitochondrial respiratory chain. Inhibition respiration can lead tricarbo...
