复杂碳水化合物如纤维素、半纤维素基本上是不能消化的，就象植物性食物中所找到的许多低聚糖、某些其它碳水化合物、树胶和纤维质材料一样。
Complex carbohydrates, such as cellulose and hemicellulose, are largely indigestible, as are a number of origins.
纤维和细小纤维悬浮于水中时，由于半纤维素、氧化纤维素和氧化木素上某些功能基的离子化，导致纤维带有负电荷。
Wood fibres and fines in an aqueous system are negatively charged due to ionization of functional groups associated with hemicellulose, oxidized cellulose and oxidized lignin.
