HUMAN NUTRITION

Detailed explanation-1: -Polysaccharides, or glycans, are polymers composed of hundreds of monosaccharide monomers linked together by glycosidic bonds. The energy-storage polymers starch and glycogen are examples of polysaccharides and are all composed of branched chains of glucose molecules.

Detailed explanation-2: -Complex carbohydrates, or polysaccharides, consist of hundreds or even thousands of monosaccharides. They include starch, glycogen, cellulose, and chitin. They generally either store energy or form structures, such as cell walls, in living things.

Detailed explanation-3: -5.3 Carbohydrates. Simple sugars, known as monosaccharides, are the building blocks of carbohydrate polymers. Unlike DNA, RNA, and proteins which are linear polymers, carbohydrates are formed by both linear and branched combinations of a wide variety of naturally occurring monosaccharides.

Detailed explanation-4: -Cellulose is composed of unbranched, parallel chains of glucose. A key feature is that the chains bond to one another to form strong fibers that serve a structural purpose. Humans do not have the enzymes necessary to break the bonds in cellulose, and any cellulose we ingest passes through our digestive systems.
