cellulose

 [sel´u-lōs]
a carbohydrate forming the skeleton of most plant structures and plant cells. It is the most abundant polysaccharide in nature and is the source of dietary fiber, preventing constipation by adding bulk to the stool. Good sources in the diet are vegetables, cereals, and fruits.
absorbable cellulose (oxidized cellulose) an absorbable oxidation product of cellulose, applied locally to stop bleeding.
cellulose sodium phosphate an insoluble, nonabsorbable cation exchange resin prepared from cellulose; it binds calcium and is used to prevent formation of calcium-containing kidney stones.

cel·lu·lose

(sel'yū-lōs),
A linear B1→4 glucan, composed of cellobiose residues, differing in this respect from starch, which is composed of maltose residues; it forms the basis of vegetable and wood fiber and is the most abundant organic compound; useful in providing bulk in the diet.
Synonym(s): cellulin
[L. cellula, cell, + -ose]

cellulose

(sĕl′yə-lōs′, -lōz′)
n.
A polysaccharide, (C6H10O5)n, that is composed of glucose monomers and is the main constituent of the cell walls of plants. It is used in the manufacture of numerous products, including paper, textiles, pharmaceuticals, and insulation.

cel′lu·lo′sic (-lō′sĭk, -zĭk) adj.

cel·lu·lose

(sel'yū-lōs)
An indigestible carbohydrate found in plants.
[L. cellula, cell, + -ose]

cellulose

A complex polysaccharide forming the structural elements in plants and forming ‘roughage’ in many vegetable foodstuffs. Cellulose cannot be digested to simpler sugars and remains in the intestine.

cellulose

a type of unbranched polysaccharide carbohydrate composed of from one to four linked (3-GLUCOSE units which can be hydrolysed by the enzyme CELLULASE. Cellulose is the main constituent of plant cell walls and is the most common organic compound on earth. It has high tensile strength because of H-bonding and is fully permeable.

cel·lu·lose

(sel'yū-lōs)
A linear B1→4 glucan; forms the basis of vegetable and wood fiber and is the most abundant organic compound.
[L. cellula, cell, + -ose]

Sol-Gel Transition of Cellulose I Silk Fibroin/[BM1MJCI Solutions
The sol-gel transition of cellulose/silk fibroin/[BMIM]Cl has been proved in our previous study [14], It is found that the gel structure is mainly formed by cellulose molecules and it can be loosened with the existence of silk fibroin.
A two-phase structure of the blend was speculated from the deviation of the tTS principle, Han plot and empirical Cox-Merz rule, the miscibility of cellulose and silk fibroin was improved with the increase of cellulose/silk fibroin concentration, which is caused by the enhanced interaction between cellulose and silk fibroin.

Recently, solid catalysts, such as carbonaceous acids, metal oxides, supported metals, H-form zeolites, acid resins, heteropoly acids, magnetic acids, and functionalized silicas, have attracted much attention as promising and appealing catalysts for the hydrolysis of cellulose into glucose due to their excellent properties, such as easy separation, recoverability and reusability from product solutions, and adjustable functional structure of catalysts [92, 98, 131, 163, 217-228].
In particular, the direct catalytic conversion of cellulose to polyols is an important part of biorefinery, which has attracted extensive interest to meet the world's energy needs [236-242].
The direct conversion of cellulose to value-added polyols in biorefinery is an attractive and promising approach.
