cellulose (redirected from cellulose acetate)

cellulose /cel·lu·lose/ (sel´u-lōs) a rigid, colorless, unbranched, insoluble, long-chain polysaccharide, consisting of 3000 to 5000 glucose residues and forming the structure of most plant structures and of plant cells.

cellulose acetate  an acetylated cellulose used as a hemodialyzer membrane.

oxidized cellulose  an absorbable oxidation product of cellulose, used as a local hemostatic.

cellulose

[sel′yoo͡lōs]

Etymology: L, cellula, little cell

a colorless, insoluble, indigestible, transparent, solid polysaccharide that is the primary constituent of the cell walls of plants. In the diet it provides the bulk necessary for proper digestive tract functioning. Rich sources are fruits, such as apples and bananas, and legumes, bran, and green vegetables, especially celery. See also dietary fiber.

cellulose (selˑ·y·lōs),

n an unbran-ched 1–4-beta-glucose polymer found in fruits, grains, seeds, and vegetables. A major dietary fiber, cellulose increases fecal size and weight because of its ability to bind water.

cellulose,

n the primary component of plant cell walls; provides the fiber and bulk necessary for optimal functioning of the digestive tract.

cellulose, oxidized

n cellulose, in the form of cotton, gauze, or paper, that has been more or less completely oxidized.

cellulose

a polysaccharide containing β1→4 linked glucose carbohydrate forming the skeleton of most plant structures and plant cells. In herbivores, digested by bacteria in the rumen or cecum, primarily to volatile fatty acids which can be used as a source of energy.
