(You can find in this post the answers to the Questions C-06, C-o7 and C-O8)

 

As discussed in a former post Polysaccharides are carbohydrates formed by more than 9 monosaccharides linked by glycosidic bonds.

 

 When they are formed by the same kind of monosaccharides, they are called homopolysaccharides, like starch, glycogen and cellulose, formed each of them by hundreds of molecules of glucose linked by glycosidic linkages.

If the polysaccharides molecules are formed by different kinds of monosaccharides, they are considered heteropolysaccharides. Hyaluronic acid, formed by thousands of alternative units of N-acetyl glucosamine and glucuronic acid, is an example of heteropolysaccharide.  

 

HOMOPOLYSACCHARIDES:

 

Cellulose

 

Cellulose is a linear polymer of D-glucose residues bonded by b(1, 4)-O-glycosidic linkages. It is the most abundant carbohydrate in nature.

 

It is formed by glucose units, linked by Beta-1, 4 O-glycosidic linkages. We can say then that, if we…
