Isotope-exchange rates at chemical equilibrium were determined for the glycogen-a-D-glucopyranose l-phosphatePi system in the presence of phosphorylase a. Exchange of 32P from a-n-glucopyranose l-phosphate (glucose-l-P) into Pi and exchange of 14C from glucose-l-P into glycogen were followed simultaneously by the use of glucose-l-P containing both isotopes. Concentrations of glucose-l-P and Pi ...

the sources of groundwater pollution such as, industrial effluents, sewage and extensive farming have lead to agrochemical pollution. mathematical modeling helps to analyze the existing situation, allows forecasting, and to evaluate the effects of changes in the surrounding water quality. the present research has been focused mainly towards understanding the various processes affecting the tran...

Recent research shows that energy metabolism can strongly influence proteostasis and thereby affect onset of aging and related disease such as Parkinson's disease (PD). Changes in glycolytic and proteolytic activities (influenced by diet and development) are suggested to synergistically create a self-reinforcing deleterious cycle via enhanced formation of triose phosphates (dihydroxyacetone-pho...

1. Incubation of cell-free extracts of methane- or methanol-grown Pseudomonas methanica with [(14)C]formaldehyde and d-ribose 5-phosphate leads to incorporation of radioactivity into a non-volatile product, which has the chromatographic properties of a phosphorylated compound. 2. Treatment of this reaction product with a phosphatase, followed by chromatography, shows the presence of two compoun...

Abstract 3-Aryloxindole derivatives were synthesized through a Friedel–Crafts-type cyclization. The reaction was catalyzed by trimethylsilyl tricyanopalladate complex generated in situ from cyanide and Pd(OAc)2. Wide varieties of diethyl phosphates derived N-arylmandelamides converted almost quantitatively into oxindoles. When N,N-dibenzylamide used instead an anilide substrate, benzo-fused δ-l...

Given consumer demand for foods with fewer artificial additives, the objective of this study was to investigate effects reduced use nitrites and phosphates on dry-fermented sausage quality. Four formulations were prepared: (1) control (using standard procedure 0.2% 110 mg/kg sodium nitrite) (2) 50% less nitrite, (3) nitrite ascorbate (225 mg/kg), (4) but no phosphates. Weight loss pH evolution ...

abstracta pot study was conducted in order to evaluate the effect of plant growth promoting rhizobia (pgpr) on canola growth and ionic composition under salt stress conditions, was conducted as factorial in randomized complete block design with three replications. salinity in four levels of 0, 3, 6 &9 ds/m were evaluated with mixture of salts nacl & mgcl2. canola seeds were inoculated with sele...

considering convergent product as an important manufacturing technology for digital products, we integrate functions and sub-functions using a comprehensive fuzzy mathematical optimization process. to form the convergent product, a web-based fuzzy network is considered in which a collection of base functions and sub-functions configure the nodes and each arc in the network is to be a link betwe...
