A hemicellulose (also known as polyose) is one of a number of heteropolymer (matrix polysaccharides), such as arabinoxylans, present along with cellulose in almost all terrestrial plant cell walls.[1] While cellulose is crystalline, strong, and resistant to hydrolysis, hemicelluloses have random, amorphous structure with little strength. They are easily hydrolyzed by dilute acid or base as well as a myriad of hemicellulase enzymes.
