(c)
To determine: The cause of endolytic as well as exolytic cleavage of glycosidic bonds by the enzymes contained by the cells which degrade amylase instead of amylopectin.
Introduction: In storage polysaccharides, the common examples of branched-chain polymers in cells are amylopectin and glycogen. Each one of them is degrade exolytically (external) by degradation of the end units of glucose.
(d)
To explain: The absence of branches in the structure of polysaccharide of cellulose.

- 11:14 structure. They provide the matrix or ground substance of extracellular tissue spaces in which collagen and elastin fibers are embedded. Hyaluronic acid, chondroitin 4-sulfate, heparin, are among the important glycosaminoglycans. 10. Glycoproteins are a group of biochemically important compounds with a variable composition of carbohydrate (1-90%), covalently bound to protein. Several enzymes, hormones, structural proteins and cellular receptors are in fact glycoproteins. Chapter 2: CARBOHYDRATES SELF-ASSESSMENT EXERCISES I. Essay questions 1.
