Pretend you are a teacher preparing a quiz for the text I will provide. 
            Each quiz question should follow the format below. 
            Ensure that you carefully recheck the questions and answers for accuracy. 
            The output should be a ready-to-use list of dictionaries for the Python eval function:

            [

                    "question": "WRITE THE QUESTION HERE",
                    "options": ["A) OPTION_1", "B) OPTION_2", "C) OPTION_3", "D) OPTION_4"],
                    "answer": INDEX_OF_CORRECT_ANSWER_IN_OPTIONS_LIST,
                    "explanation": "EXPLAIN WHY THE ANSWER IS CORRECT"

            ]

Amylose 
2) Glycogen (animal 
starch) 
The major form of animals storage polysaccharide. 
Found mainly in the liver (represent ≈10% of liver mass) & 
skeletal muscle (about 1-2% of muscle mass). 
Similar to amylopectin, but it has many branched points &  short 
branches 
It gives red color with iodine test. 
3) 
Cellulose 

It’s the most abundant of CHO & organic substances on earth. 

About 33 % of plant matter is cellulose. 

A polymer of linear nonbranching β-D-glucose, linked by β-(1→4) gly  
bonds. 

There’re no enzymes in human or animals that are able to hydrolyzed  the -
(1→4) gly bond of cellulose but some animals can hydrolyze  cellulose to 
obtain glucose by some bacteria (has cellulase enzyme)  present in their gut. 
2) Insoluble in water & most organic solvent 
1) Tasteless & odorless 
3) Structural material of plant         4) Gives no color with Iodine test 
Properties of cellulose 
4) Inulin 
A polymer of D-fructose linked together by -(2→1)-gly 
bonds 
Found in of onion, garlic & roots of some plants. 
It’s used to measure renal function & acts as a prebiotic. 
 
   5) Dextrins 
A polymers of D-glucose units linked by α-(1→4) or α-(1→6) 
gly  bonds & produced by the hydrolysis of starch. 
Used in infant feeding & as glues in postage stamp & envelope 
adhesive 
6) 
Dextran 
A branched polymer of D-glucose linked by α-(1→6) gly 
bonds in  linear chain & by α-(1→3) gly bonds in 
branches. 
It’s synthesized from sucrose by certain bacteria. 
Dental plaque is rich in dextran. 
Used as plasma expander (increased blood 
volume), when given  intravenous, in case of 
haemorrhage & prevent thrombosis. 
 
7) 
Agar 
A polymer of galactose, present in sea weeds. 
Used as laxative & for preparation of bacterial & fungi 
culture media & electrophoretic separation. 
b) 
Heteropolysaccharides 
A polymer consisting of 2 or more different monosaccharides 
There are 3 types 
1)
glycosaminoglycans, 
2)
proteoglycans, 
3)
Glucoproteins 
 
1) Glycosaminoglycans (mucopolysaccharides) (GAGs) 
are linear polymers with disaccharide repeating units. 
These units consist of: acidic and amino sugar 
1) Hyaluronic acid 
• It’s the most abundant GAGs in the synovial fluid of the joints 
&  vitreous humor of the eye. 
• Found in connective tissues & skin. 
Functions: 
1.
Acts as a lubricant in joints. 
2.
Responsible for the resilience of cartilage. 
3.
Involved in tissue repair. 
4.
Has a role in movement & proliferation of cells. 
2) Chondroitin sulphate A & C 
• Present in cartilage, cornea of the eye, tendons, ligaments,  
bones, & connective tissue matrix. 
Functions 
• An important structural component of cartilage & provides much of  
its resistance to compression. 
• Used as dietary supplement for treatment of osteoarthritis. 
3) Keratan sulfate 
• Found in cornea, cartilage & intervertebral disks.
