The present work displayed the great importance of 2D NMR analysis on the structure elucidation of this sulfonic acid functionalized liquid salt. The results of NMR analysis demonstrate that 4-imidazole-1-yl-butane-1-sulfonic acid did not exist and really a mixture of zwitterionic and ionic ...
aDifferent zone of the infected PNL was harvested for chemical analysis. Zone I: lesion area, Zone II: healthy area in the same leaf, Zone III: healthy area in the neighboring leaf.bHPLC-UV chromatograms of methanolic extracts of healthy leaf from the non-infected plants (CON) and PNL wi...
The imidazole N–H is involved in an intermolecular hydrogen bond with the hydrazide nitrogen forming a 1-D supramolecular structure. In the (μ-imidazolate) dicopper(II) complex K[{Cu(Sah)}2Im], each copper(II) atom is in a distorted square-planar environment where the hydrazone ligand ...

(Brew, 2013). The tertiary structure of the protein is globular, with two lobes forming a calcium-binding site; therefore, α-lac exists in two forms, calcium-bound (holo- α-lac) and calcium-depleted (apo-α-lac) (Chatterton et al., 2006;Permyakov and Berliner, 2000). α-Lac is ...
