Definition
Glossary of "Plant Biology (1st ed.)" by Graham et al. (2003)
- A carbohydrate formed of long chains of glucose molecules that is a major component of plant cell walls (and those of some protists and some bacteria). Cellulose is also produced by various bacteria for use as an attachment material.
Glossary of Plant Systematics (1st ed.) by Simpson (2006)
- A polymer of glucose sugar units (= polysaccharide) in which the glucose molecules are chemically bonded in the beta-1,4 position (= β-1,4-glucopyranoside); a major component of the cell wall of green plants. A polysaccharide of glucose units (β-1,4-glucopyranoside), a primary component of plant cell walls.
Glossary of "The Cell (5th ed.)" by Alberts et al. (2008)
- Structural polysaccharide consisting of long chains of covalently linked glucose units. Provides tensile strength in plant cell walls.
Glossary of "Evolution of Plants (2nd ed.)" by Willis & McElwain (2014)
- A polysaccharide composed solely of glucose units linked by glycosidic bonds.
解説
- 地球上には多くの炭水化物が存在するが，もっとも多く存在するのがセルロースである．
- セルロースは複数の糖が結合した天然の高分子化合物で，食物繊維の一つとして知られる．
- セルロースは植物の細胞壁に多く含まれ，植物中で繊維状に存在し，紙や綿として古くから利用されている．
- 反芻動物は共生微生物の力を借りてセルロースなどを発酵・分解することで利用している．
