Pikovskoi, I. I. published the artcileStudy of the sedge (Carex) lignin by high-resolution mass spectrometry and NMR spectroscopy, Category: isoquinoline, the main research area is Carex lignin NMR spectra protein structure.
A combination of high-resolution mass spectrometry based on an orbital ion trap and 2D NMR spectroscopy was first applied to the characterization of the structure of poorly studied lignins of herbaceous plants using dioxane lignin from sedge (Carex) as an example. Macromols. of the Carex lignin are found to be constructed from guaiacyl, syringyl, and p-hydroxyphenyl structural units in a ratio of 57:22:21 bound mainly by ether β-O-4 bonds. The key role of p-hydroxycinnamic acids in the formation of the lignin structure and ester bonds with polysaccharides was shown. A possible structural formula of the macromol. fragment of the Carex lignin was proposed on the basis of an anal. of the 2D NMR spectra (HSQC).
Russian Chemical Bulletin published new progress about Collision-induced dissociation. 86-51-1 belongs to class isoquinoline, name is 2,3-Dimethoxybenzaldehyde, and the molecular formula is C9H10O3, Category: isoquinoline.
