from The Century Dictionary and Cyclopedia
- n. One of the group of complex carbohydrates which yield simple sugars when hydrolyzed by the action of enzymes, acids, or alkalis. The term sometimes includes the disaccharides and trisaccharides, but is more correctly limited to substances of the general formula (C6H10O5)n, where n is probably a large number. Starch, cellulose, dextrine, glycogen, and gums are polysaccharides.
