Second, initiation and propagation of electrical signalling by voltage-gated ion channels with the key words calcium antagonists, dihydropyridines, benzodiazepines, phenylalkylamines and the corresponding drugs, in particular nitrendipine and its derivatives, amlodipine, and verapamil. Third, angiotensin I ...
aAbstract: This paper is a hybrid starting with an overview and history of biodiesel synthesis and finishing with a description with some of our latest unpublished data. Initially, we examine “green” ways of obtaining biodiesel using ionic liquids, which can have an acidic or basic functionality...
aSince the 2-nitrobenzenesulfonamide group is stable under acidic [HCl (10 eq), MeOH, 60°C, 4 hr] as well as basic [NaOH (10 eq), MeOH, 60°C, 4 hr] conditions, it can be used extensively for protection of primary and secondary amines. Because of the mild conditions and easy ...

At higher pH (>pKa), these amines are deprotonated which, in turn, makes chitosan neutral and insoluble [48]. The reasons that chitosan can be applied well in the analysis of drug substances, envi- ronment pollutants, industrial materials, and food compounds are that they can form the film...

peroxiredoxin; TR: thioredoxin; GR: glutaredoxin; GPX: glutathione peroxidase; GST: glutathione S-transferase Up-regulation is marked green and down-regulation is marked red (VIT_17s0000g08030) indicates that this step of poly- amines metabolism was also regulated at transcriptome level (Additional ...
Hydrolysis of the Si–OR bond in silanes occurs faster in an acidic/basic environment compared to a neutral solution. At a pH below the isoelectric point (IEP of silica—2.0), the silica is positively charged, and its charge density increases with a decrease in pH. In reaction mixtures ...
Table 15 describes the proprieties of different metal amines that can be used in this case [116]. Table 15. The characteristics of various metal amine complexes [116]. Much research in this field is required to improve this way of storage. As a result, future development should concentrate...
Simple oxides can be classified on the basic of their acidic, basic or amphoteric character. an oxide that combines with water to give an acid is termed acidic oxide (i.e., SO2,Cl2O7,CO2,N2O5). for example, SO2 combines with water to give H2SO3, an acid. Q. If, Then select ...
