Carnosine was successfully N-acylated in 2-methyl-2-butanol, and a yield of 39% was obtained when improving the substrate solubility: a better dispersibility was obtained by application of a high pressure on the reaction medium just before starting the reaction....
A total of 9,647 SdO representative of 44,622 transcripts were differentially expressed (DE) between CRD and RMN (FDR < 0.01) (Additional file1: Table S10). Overall, the DE SdO clustered in two groups consisting of 7,038 SdO more expressed in RMN samples, and 2,609 SdO more expre...
QD inks developed in various solvents, including N-methyl-2-pyrrolidone (NMP) with 1 wt% of n-butylamine (BTA), provide stable formulations over several days and high-resolution printing of a thin uniform film [120]. Despite the significant potential, the perovskite stability in ambient ...
(w/v) ninhydrin in butanol for aminolipids (specific for amino groups), Dittmer and Lester’s Zinzadze reagent for phospholipids (specific for phosphates), and α-naphthol for glycolipids (specific for sugars). Peptidoglycans were extracted and analyzed for the diagnostic amino acids from whole ...
INAKI' and Kiichi TAKEMOTO Department of Applied Fine Chemistry, Faculty of Engineering, Osaka University, Suita, Osaka 565, Japan (Received May 25, 1988) ABSTRACT: Nucleic acid analogs were prepared by grafting cytosine and hypoxanthine derivatives containing hydroxyl groups onto linear polyethyleneimine...
in the same molecule and (b) a degree of polymerization of from 2 to 10 and the salts of the polyamide formed by the salt of the terminal carboxylic acid group, the terminal amine group or the terminal carboxylic acid and terminal amine groups of the polyamide and (2) an aqueous ...
These residues form two highly hydrophobic tunnels within the membranes and contribute to the polar regions in the cavity that can accommodate the lipophilic tails and phosphate groups of substrates (Figure 3B), respectively. The molecules of n-dodecyl-N,N-dimethylamine-N-oxide (LDAO; used for ...
On the basis of this classification, four main groups of crude oils and materials can be distinguished, as shown in the table below [http://www.seaforecast.cnr.it/sosbonifacio/index.php/Il-Progetto/inquinamento-marino-da-idrocarburi.html]: ...
Higher cationic substitution in addition to build-up, causes discoloration or staining of substrates such as textiles, hard surfaces such as bathtubs, wash sinks, ceramic surfaces, porcelain surfaces. None of these commercially available polymers are significantly modified with hydrophobic groups. It ...
being at least one tri-functional epoxy monomer (b) selected from monomers comprising three glycidyl groups. The combination of very interesting performances of coatings obtained by curing of compositions containing such high amounts of polyfunctional epoxy monomers are demonstrated in Examples 1 and 2...
