Lignin carbohydrate complexes

The conclusion that solid-state spectra provide evidence for a lignin-carbohydrate complex is of special interest. Solid-state spectra of lignin fractions obtained by ball milling and extraction with dimethyl sulfoxide exhibit carbohydrate signals and vice...

Lignin is linked through covalent bonds (ester and ether) to hemicelluloses. The two macromolecules then constitute the lignin-carbohydrate complex (known as LCC). As the hemicelluloses can be linked to cellulose through hydrogen bonding, the LCC is capable to assemble the cellulose microfibrils (Figure 5.3). 

Many studies have indicated that covalent linkages must exist between lignin and wood polysaccharides. Separation and analysis of lignin -carbohydrate complexes (LCC) have led to the conclusion that the hemicel-lulose components (xylan and galactoglucomannans in softwood) are bound to lignin mainly through arabinose, xylose, and galactose moieties as shown in Fig. 4-10.
