such as bleach and ammonia, are basic, as is sodium hydroxide. Citric juices, coffee and wine are acidic. Solutions with the word "acid" in them, such as stomach acid and hydrochloric
79,80. Briefly, a soil slurry was prepared for each sample by blending 1 g of peat with 125 ml of sodium acetate buffer (50 mM, pH 6.2). The soil slurry was then transferred to a 96-well flat-bottom black microplate which included a buffer-only control column, as well as ...
(P-loop, see sequence alignment) wraps the triphosphate, and the P-loop lysine forms a hydrogen bond with the phosphate group; the first acidic D/E of the Walker B motif (DExx box) coordinates a Mg2+ ion and hydrogen-bonds with ATPγS, and the Sensor-1 residue T/N and the basic ...
Consistent with the conservative replacement of two acidic residues by two others, a similar inhibitory effect on ATP hydrolysis activity was observed as for the native AtpΘ protein. In contrast, the introduction of a single histidine residue at this position (E28H; AtpΘ_H in Figure 5D and ...
Aluminium hydroxide is amphoteric, i.e., it has both basic and acidic properties. Closely related are aluminium oxide hydroxide, AlO(OH), and aluminium oxide or alumina (Al2O3), the latter of which is also amphoteric. These compounds together are the major components of the aluminium ore ...
We show that astrocytes, as judged by glial fibrillary acidic protein (GFAP) expression, never emerge from neuroepithelial cells on embryonic day (E) 11.5 even when STAT3 is activated, in contrast to E14.5 neuroepithelial cells. A CpG dinucleotide within a STAT3 binding element in the GFAP ...
The excitation spectrum of Keima shifts from 458 nm (green; mitochondria at neu- tral pH) to 561 nm (red; mitochondria under acidic pH) when mitochondria are delivered to acidic lysosomes [38, 39]. Compared with normoxia, hypoxia treatment induced mitochondrial delivery to lysosomes, an ...
(Fig. 1). As reported before, two endothermic peaks with a pre-transition at ~36 °C and a main denaturational transition at ~42 °C is observed for collagen in acidic solut 胶原的耐热性依赖性在12.4毫米钠醋酸盐缓冲(酸碱度4)对Al2 (SO4)的集中3由US-DSC学习了(。 1). 如报告前面,二个...
We hypothesized that a thioglycoligase with these properties may be able to function in an acidic environment instead of the conventional neutral/basic pH. Under these conditions, many potential acceptors, such as carboxylic acids and phosphorylated derivatives would be neutral and therefore able to ...
For LC/MS and LC/MS/MS, samples were reconstituted in acidic or basic LC-compatible solvents containing >11 injection standards and run on a Waters ACQUITY UPLC and Thermo-Finnigan LTQ mass spectrometer, with a linear ion-trap front-end and a Fourier transform ion cyclotron resonance mass ...
