The metabolic fate of C14 labeled pentoses in man.
The role of pentoses in intermediary metabolism has received much attention within the past few years. The phosphate esters of D-ribose, D-ribulose and D-xylulose have been identified as key intermediates in the pentose phosphate pathway of glucose metabolism in both plant and mammalian tissue (1). More recently, another alternate pathway of glucose dissimilation, the uronic acid pathway, has b...

15 صفحه اولStudies on the physical state of water in living cells and model systems. XI. The equilibrium distribution coefficients of pentoses in muscle cell water: their dependence primarily on the molecular weights of the pentoses and lesser dependence on their stereospecificity.
Studies of the metabolism of four pentoses (D-, and L-arabinose; D-, and L-xylose) in frog muscle at 0 degree C revealed that all are metabolized at extremely slow rates. As a result, the metabolic degradation of these pentoses does not significantly affect their equilibrium distribution in muscle cells at this temperature at least. Of the four stereoisomers, three (L-xylose, D-arabinose, L-ara...
متن کاملsimulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water
abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...
Studies on the Sensitization of Animals with Simple Chemical Compounds
The fate of (14)C-labeled allergens injected intradermally into guinea pigs, namely picryl chloride (PCl*) and 2:4 dinitrochlorobenzene (DNCB*), was followed during the induction period of delayed hypersensitivity. Both chemicals were applied in a single injection into one ear in amounts that approached their minimal sensitizing doses (PCl, 0.25 microg; DNCB, 5.0 microg). Radioactivity in the v...
