Apolipoprotein B-100 (apoB-100) appears in three forms in the endoplasmic reticulum of Hep G2 cells: (1) tightly bound to the membrane, ie, not extractable by sodium carbonate. This form is glycosylated but protease sensitive when present in intact microsomes, suggesting that it is only partially translocated to the microsomal lumen; (2) extractable by sodium carbonate and present on low-densit...

The objective of this work was to study the effect of mixed culture solid substrate fermentation of C. tropicalis ZD-3 with A. niger ZD-8 on detoxification of cottonseed meal (CSM), and to investigate the effect of fermentation period, proportion of CSM in substrate, sodium carbonate, minerals and heat treatment on the reduction of free gossypol levels during mixed culture solid substrate ferme...

Toxicological summary for sodium metasilicate [6834-92-0] and its 01/2002 pentahydrate [10213-79-3] and nonahydrate [13517-24-3] i Executive Summary Basis for Nomination Sodium metasilicate was nominated for subchronic inhalation toxicity testing based on the large number of individuals occupationally exposed to the compound, evidence for biological activity, and the gaps in available toxicity ...

The emission of CO₂ has been considered a major cause of greenhouse effects and global warming. The current CO₂ capture approaches have their own advantages and weaknesses. We found that free-flowing hydrated sodium carbonate (Na₂CO₃) powders with 30 wt % water can achieve a very high CO₂ sorption capacity of 282 mg/g within 60 min and fast CO₂ uptake (90% saturation uptake within 16 min). The ...

We report here experimental evidence for the hydrothermal formation of a pure organic molecule, phenol, from the reaction of carbonate with water in the presence of iron powders.

Sodium bicarbonate is sometimes used to aid in the extraction of total polyphenols. Its main effect increase pH solution. Raising can cause changes chemical structure This lead variations their biological properties, solubility and stability. work studied sodium carbonate on by aqueous decoction polyphenols from leaves Combretum micranthum. The content phenolic compounds extracts was estimated ...

We have developed the first example of hypervalent iodine(V)-catalyzed regioselective oxidation of phenols to o-quinones. Various phenols could be oxidized to the corresponding o-quinones in good to excellent yields using catalytic amounts of sodium salts of 2-iodobenzenesulfonic acids (pre-IBSes) and stoichiometric amounts of Oxone® as a co-oxidant under mild conditions. The reaction rate of I...

A spectrofluorimetric method for the determination of paracetamol is presented, based on the oxidation of the analyte to give the fluorophore 2,2'-dihydroxy-5,5'-diacetyldiaminebiphenyl. Sodium hypochlorite was used as an oxidizing reagent and the optimum pH was found to be 10.0 (sodium carbonate-boric acid buffer solution). The linear concentration range of application was 0.1-100.0 micrograms...
