Polysaccharide

Polysaccharide. Polysaccharides are polymeric carbohydrate structures, formed of repeating units (either mono- or di-saccharides ) joined together by glycosidic bonds . These structures are often linear, but may contain various degrees of branching.

  1. Polysaccharide Polysaccharides are polymericcarbohydrate structures, formed of repeating units (either mono- or di-saccharides) joined together by glycosidic bonds. These structures are often linear, but may contain various degrees of branching. Polysaccharides are often quite heterogeneous, containing slight modifications of the repeating unit.

  2. Depending on the structure, these macromolecules • can have distinct properties from their • monosaccharide building blocks. • They may be amorphous or even insoluble in water. • When all the monosaccharides in a polysaccharide • are the sametype the polysaccharide is • called a homopolysaccharide, but when more than • one type of monosaccharide is present they are • called heteropolysaccharides. • Examples include storage polysaccharides such as • starch and inulin, • and structural polysaccharides such as cellulose.

  3. Glycosidic bond • In chemistry, a glycosidic bond is a type of that joins a carbohydrate (sugar) functional group molecule to another group, which may or may not be another carbohydrate.
