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. The glucose monomers are linked by α glycosidic bonds.

WebbName three carbohydrates that can be built using only glucose monomers. 1. Discuss how two polysaccharides, starch and cellulose, each having the same subunit (glucose), have completely different properties. Why can we digest starch but not cellulose 2. WebbWhen beta-glucose (the —OH is on the same side as the C6 carbon) forms the polymer cellulose, the linkage occurs through beta 1–4 glycosidic bonds. This arrangement allows the hydroxyl groups sticking off the sugar backbone to form hydrogen bonds (see Figure 3.13 , p. 19 , Figure 4.7B , p. 26 and Figure 9.7 ) with other strings of cellulose. http://www.differencebetween.net/language/words-language/difference-between-glucose-and-cellulose/ black ants and buddhists

Starch and Cellulose: How Stereochemistry Brings Such Different ...

WebbStarch is constructed from two different polysaccharides: Amylose (10 - 30% of starch) Unbranched helix-shaped chain with 1,4 glycosidic bonds between α-glucose molecules. The helix shape enables it to be more compact and thus it is more resistant to digestion. Amylose – one of the two polysaccharides that is used to form starch (the storage ... WebbStarch is a polysaccharide made up of repeating glucose subunits. It is made up of two components, amylose and amylopectin. Amylose consists of a linear chain of glucose molecules attached via alpha 1-4 glycosidic bonds. It makes 20-30% of starch and can exist in one of the three forms; Amorphous chain.
