  author={Mikhail Yu Balakshin and Ewellyn A. Capanema and Hanna S. Gracz and Hou-min Chang and Hasan Jameel},
A quantitative approach to characterize lignin–carbohydrate complex (LCC) linkages using a combination of quantitative 13C NMR and HSQC 2D NMR techniques has been developed. Crude milled wood lignin (MWLc), LCC extracted from MWLc with acetic acid (LCC-AcOH) and cellulolytic enzyme lignin (CEL) preparations were isolated from loblolly pine (Pinus taeda) and white birch (Betula pendula) woods and characterized using this methodology on a routine 300 MHz NMR spectrometer and on a 950 MHz… CONTINUE READING
