Hemicellulose is een verzamelnaam voor een reeks zeer nauw verwante koolhydraten die worden gemaakt in planten. Hemicellulose is een belangrijke component van de celwand en vormt meestal een soort matrix waarin cellulosemoleculen ingebed liggen. Waar cellulose uitsluitend is opgebouwd uit glucose-elementen, via β-1,4-bindingen aan elkaar gelinkt tot een polymere keten, bestaat hemicellulose uit soortgelijke ketens, maar op basis van een aantal andere suikers, zoals A hemicellulose (also known as polyose) is one of a number of heteropolymers (matrix polysaccharides), such as arabinoxylans, present along with cellulose in almost all terrestrial plant cell walls. Cellulose is crystalline, strong, and resistant to hydrolysis. Hemicelluloses are branched, shorter in length than cellulose, and also show a propensity to crystallize. They can be hydrolyzed by dilute acid or b…

Lignocellulosic biomass contains cellulose, hemicellulose, lignin, and ash combined in a complex structure (Table 3-6). Pre-treatment increases the crystallinity of cellulose, while removing lignin and other inhibitors, thereby enabling its enzymatic degradation. In addition, pretreatment may increase ... scouts kings lynn
