"Group of gummy substances intermediate between cellulose & sugars." [ChemIDplus] "Water-extracted Hemi-cellulose and other naturally occurring wood constituents (wood sugars/wood molasses) mixed with water." [Temple-Inland MSDS] "A hemicellulose (Also known as Polyose) is any of several heteropolymers (matrix polysaccharides), such as arabinoxylans, present along with cellulose in almost all plant cell walls. While cellulose is crystalline, strong, and resistant to hydrolysis, hemicellulose has a random, amorphous structure with little strength. It is easily hydrolyzed by dilute acid or base as well as myriad hemicellulase enzymes." [Wikipedia]
