This adhesion depends upon various cross-links; ionic, covalent or weak interactions between the macromolecules of the adjacent cell walls. In sugar-beet ( Beta vulgaris L. Aztec) root parenchyma, cell-cell adhesion is disrupted by successive extractions with a calcium-chelating agent (imidazole) ...
rather they are mixtures/solutions of chemicals. It is not uncommon for wide range of molar ratios of a mixture to be lumped together as "synonyms" of the same "chemical". In some instances chemicals that are very similar from a health & safety and/or regulatory standpoint also may have ...
“linker” means a molecule that joins the carbohydrate targeting domain with the nucleic acid binding domain. In certain aspects, the sugar targeting domain and the nucleic acid binding domain are physically linked by, for example, covalent chemical bonds, physical forces such van der Waals or ...
For the development of PBA-based electrochemical sensing systems or sensors, PBA is modified with a redox-active marker, because PBA itself is electrochemically inactive, and ferrocene derivatives are often employed for this purpose. Ferrocene-modified PBAs have been used as redox-active additives in...
Here we show that sugars, in particular, fructose, are capable of directing the self-assembly of highly insoluble curcumin resulting in the formation of well-defined capsules based on non-covalent forces. Simply by mixing an aqueous solution of fructose and curcumin in an open vessel leads to ...
enzymes such as the endoenzymes9 that cleave the β-(1 → 4)-glycosidic lin- ear main chain randomly, the exo- and β-enzymes9,10 for the non-reducing ends, and the α-glucuronidase and α-L-arabinofuranosidase enzymes for the α-(1,2) and α-(1,3) covalent side chains...
and ionic-exchange membranes. In nanofiltration, the sugar flux increases with the presence of ions of increasing hydration energy. Instead, inverse linear correlations were found between the hydration energy and the sugar fluxes through ion exchange membranes. Finally, an empirical model is proposed ...
Whether Dissolving Is a Chemical or Physical Change Any time you dissolve a covalent compound like sugar, you're looking at aphysical change. The molecules get further apart in the solvent, but they don't change. However, there's a dispute about whether dissolving an ionic compound (like sal...
that is optimum conditions for reductive amination, it is necessary that an amino group is not protonated. Therefore, an aromatic amino group is preferable in which a non-covalent electron pair is present on a nitrogen atom due to aromatic conjugation even at a pH in the range from 3 to 4...
glucose-binding residues as the feature values (McDonald and Thornton, 1994).Tsai et al. (2012)developed a sugar-binding site prediction method based on three-dimensional probability density maps, representing the distributions of 36 non-covalent interacting atom types aroundprotein surfaces. The ...
