HUMAN NUTRITION

Detailed explanation-1: -Many complex carbohydrates are unsubstituted at their reducing ends and are referred to as polysaccharides; examples include the oligosaccharides of milk, the cellulose of plant cell walls, and storage forms such as starch and glycogen.

Detailed explanation-2: -Dextran is a complex polysaccharide. It is produced from sucrose by the bacterium Leuconostoc mesenteroides. The bacterium produces dextran by sucrose fermentation.

Detailed explanation-3: -Starch, glycogen, cellulose, and chitin are primary examples of polysaccharides.

Detailed explanation-4: -Polysaccharides are long chains of monosaccharides linked by glycosidic bonds. Three important polysaccharides, starch, glycogen, and cellulose, are composed of glucose. Starch and glycogen serve as short-term energy stores in plants and animals, respectively.
