Cellulose yog macromolecular polysaccharide uas muaj cov piam thaj. Insoluble nyob rau hauv dej thiab cov organic solvents. Nws yog qhov tseem ceeb ntawm cov nroj tsuag cell phab ntsa. Cellulose yog cov feem ntau nthuav dav thiab ntau polysaccharide nyob rau hauv cov xwm, accounting rau ntau tshaj 50 feem pua ntawm cov pa roj carbon ntsiab lus nyob rau hauv cov nroj tsuag lub nceeg vaj. Cov ntsiab lus cellulose ntawm paj rwb yog ze rau 100 feem pua, uas yog lub ntuj ntshiab tshaj plaws ntawm cellulose. Hauv cov ntoo, cellulose suav rau 40-50 feem pua, thiab 10-30 feem pua hemicellulose thiab 20-30 feem pua lignin.
Cellulose yog cov txheej txheem tseem ceeb ntawm cov nroj tsuag phab ntsa, uas feem ntau yog ua ke nrog hemicellulose, pectin thiab lignin. Nws hom kev sib xyaw ua ke thiab qib kawm muaj kev cuam tshuam zoo rau kev ntxhib los mos ntawm cov zaub mov cog. Kev hloov ntawm kev ntxhib los mos ntawm cov nroj tsuag thaum lub sij hawm ripening thiab post-ripening yog tshwm sim los ntawm kev hloov ntawm pectin tshuaj. Cellulase tsis muaj nyob rau hauv lub plab zom mov ntawm tib neeg lub cev, thiab cellulose yog ib qho tseem ceeb noj fiber ntau. Ib qho ntawm feem ntau nthuav dav thiab ntau polysaccharides nyob rau hauv cov xwm.
