(a)
Interpretation:
The polysaccharide A and B need to be identified as amylopectin or glycogen. The polysaccharide containing
Concept Introduction:
Polysaccharides contain three or more monosaccharides joined.
Amylopectin is one of the common forms of the starch and it is the branch form of the starch. Starch is the main carbohydrate found in the seeds and roots of plants. Corn, rice, wheat, and potatoes are common foods that contain a great deal of starch. Starch is a
Glycogen is the major form in which polysaccharides are stored in animals. Glycogen, a polymer of glucose-containing a-glycosidic bonds, has a branched structure like amylopectin, but the branching is much more extensive.
(b)
Interpretation:
The polysaccharide stored in the liver needs to be determined.
Concept Introduction:
Polysaccharides contain three or more monosaccharides joined.
Amylopectin is one of the common forms of the starch and it is the branch form of the starch. Starch is the main carbohydrate found in the seeds and roots of plants. Corn, rice, wheat, and potatoes are common foods that contain a great deal of starch. Starch is a polymer composed of repeating glucose units joined in a-glycosidic linkages.
Glycogen is the major form in which polysaccharides are stored in animals. Glycogen, a polymer of glucose-containing a-glycosidic bonds, has a branched structure like amylopectin, but the branching is much more extensive.
(c)
Interpretation:
The polysaccharide present in bread and pasta needs to be determined.
