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.

ox·i·dized cel·lu·lose

1. cellulosic acid in the form of an absorbable gauze; used as a hemostatic in operations in which ligation is not feasible because cellulosic acid has a pronounced affinity for hemoglobin and produces an artificial clot;
See also: oxycellulose.

2. a sterile absorbable substance prepared by the oxidation of cotton containing not less than 16% and not more than 22% of carboxyl.
See also: oxycellulose.
