Polysaccharides are among the most widespread organic compounds in the plant kingdom and used in many applications [144]. Polysaccharides play essential roles in the life processes of all plants. They can be divided into several broad groups according their functions, i.e., structural polymers (cellulose), protective polysaccharides (pectin and hemicelluloses) and reserve polysaccharides (starch). Further, polysaccharides can form glycoconjugates with proteins and lipids resulting in biological macromolecules in the cell wall and cell membranes, and play important roles in many physiological and biochemical processes.
