polysaccharide

 [pol″e-sak´ah-rīd]
a carbohydrate which, on acid hydrolysis, yields many monosaccharides.

pol·y·sac·char·ide

(pol'ē-sak'ă-rīd),
A carbohydrate containing a large number of saccharide groups; for example, starch. Compare: oligosaccharide.
Synonym(s): glycan

polysaccharide

/poly·sac·cha·ride/ (-sak´ah-rīd) a carbohydrate that on hydrolysis yields many monosaccharides.

polysaccharide

(pŏl′ē-săk′ə-rīd′) also

polysaccharid

(-rĭd) or

polysaccharose

(-rōs′, -rōz′)
n.
Any of a class of carbohydrates, such as starch and cellulose, consisting of a number of monosaccharides joined by glycosidic bonds.

polysaccharide

[-sak′ərīd]
Etymology: Gk, polys + sakcharon, sugar
a carbohydrate polymer that is formed from three or more molecules of simple carbohydrates. Examples of polysaccharides are dextrin, starch, glycogen, cellulose, gums, and insulin.

pol·y·sac·char·ide

(pol'ē-sak'ă-rīd)
A carbohydrate containing a large number of saccharide groups (e.g., starch).
Compare: oligosaccharide
Synonym(s): glycan.

polysaccharide

A POLYMER of linked monosaccharide molecules. Thus, glycogen is a polysaccharide of glucose units. Like proteins, polysaccharides may have molecular weights of several million. The polymer is often branched. They include glycogen, starch and cellulose.

polysaccharide

a large carbohydrate molecule with a chain-like or branched structure, made up of many MONOSACCHARIDE units joined together by CONDENSATION REACTIONS. Although most polysaccharides have a terminal monomer present as a REDUCING SUGAR, this forms only a small part of the whole molecule and thus most polysaccharides do not act as reducing sugars. Polysaccharides are insoluble and unsweet, and are important as storage molecules (e.g. STARCH, inulin and GLYCOGEN) and as reinforcing materials (e.g. CELLULOSE of plant cell walls, CHITIN of crustacean and insect cuticles).

polysaccharide

complex sugar, e.g. starch

pol·y·sac·char·ide

(pol'ē-sak'ă-rīd)
A carbohydrate containing a large number of saccharide groups (e.g., starch).
Synonym(s): glycan.

polysaccharide,

n a complex carbohydrate containing a large number of saccharide groups such as starch.

polysaccharide

a complex carbohydrate which, on acid hydrolysis, yields many monosaccharides.
