二维HSQC(Heteronuclear Single Quantum Coherence)是一种常用的核磁共振(NMR)技术,可以用于分析木质素的转化组分。本文将阐述二维HSQC半定量分析木质素转化组分的原理、方法以及研究进展。 一、二维HSQC技术原理 二维HSQC技术是一种基于磁共振现象的NMR技术,可以用于分析复杂混合物中的化学成分。其基本原理是利用核磁共振...
In order to quantify the sugar concentrations of samples taken during the fermentation of dilute acid hydrolyzed hemicellulosic extracts a two dimensional heteronuclear single quantum coherence (2D-HSQC) technique was used. The addition of the 13C axis resulted in almost no overlapping of the peaks ...
Herein, we describe factors that should be considered when setting up non-uniformly sampled 2D-1 H,13 C HSQC NMR experiments for MFA and provide a standard protocol for users to follow.doi:10.1002/mrc.5089Mark JeevesHenry Wellcome Building for Biomolecular NMR Spectroscopy, Institute of Cancer ...
