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. 

Lignin carbohydrate complexes (LCC) in mangrove, ohirugi [Bruguiera gymnorrhiza (L.) Lamk.] and buna [Fagus crenata BL] were studied using Raman spectroscopy the LCCs were found to be similar [44]. 

There is numerous evidence that lignin and polysaccharides are covalently linked, forming manifestations of the so-called lignin-carbohydrate complex (LCC) [2,7,17-19]. In spite of there being relatively low amounts of these linkages in wood [20,21], they play a very important role, as almost all wood lignin is covalently linked to polysaccharides, mainly to hemicelluloses [22]. There are three types of LCC linkages benzyl ether, phenyl...

Lignin carbohydrate complexes (LCC) as introduced by Bjorkman (1952)(22) contain both, hydrophilic carbohydrates and more hydrophobic lignin. The formation of a micelle based on LCC has been suggested by Yaku et al. 919) 23). The interaction between lignin and carbohydrate determines the formation of micelles.
