Nettet15. nov. 2024 · Cellulose and hemicellulose can be transformed to added-value chemicals and fuels, such as, ethanol, soap, pulp, hydroxymethylfurfural (HMF), γ-valerolactone (GVL) and alkanes (Hanson et al. 2009; Zakzeski et al. 2010; Xu et al. 2014 ). Nettet23. mar. 2015 · Cellulose and chitosan have similar molecular structures, with the same b-glycoside linkages. The main difference is the presence of primary amino groups at the C-2 positions in chitosan, where cellulose has hydroxyl groups. The presence of active groups in chitosan’s molecular structure allows for easy chemical modification. bydureon bcise 2 mg/0.85 ml atin
