Detailed explanation-1: -Capsular polysaccharides are water-soluble, commonly acidic, and have molecular weights on the order of 100, 000 to 2, 000, 000 daltons. They are linear and consist of regularly repeating subunits of one to six monosaccharides.

Detailed explanation-2: -What are Polysaccharides? Polysaccharides are major classes of biomolecules. They are long chains of carbohydrate molecules, composed of several smaller monosaccharides. These complex bio-macromolecules functions as an important source of energy in animal cell and form a structural component of a plant cell.

Detailed explanation-3: -All the other statements are correct, as polysaccharides are formed by glycosidic linkages of monosaccharide units to form a long unbranched or branched chains. They are insoluble in water and are important for storage as glycogen or starch and for structural purposes as chitin or cellulose etc.

Detailed explanation-4: -As in most oligosaccharides, the monosaccharide units in polysaccharides are joined together in a head-to-tail fashion by glycosidic linkages. Also like oligosaccharides, polysaccharide molecules can be either linear or branched. All polysaccharides, therefore, have one, and only one, reducing end.
