ABSTRACT
The structural materials produced by plants to form cell walls, leaves, stems, and stalks are composed primarily of three different types of biobased macromoles, which are typically classied as cellulose, hemicellulose, and lignin. These biobased macromolecules are collectively called lignocellulose, lignocellulosic biomass, or lignocellulosic materials. A generalized plant cell wall structure is like a composite material in which rigid cellulose bers are embedded in a cross-linked matrix of lignin and hemicellulose that binds the cellulose bers, as illustrated in Figure 10.1.
