Chapter 13: Q. 13.50 (page 461)

Give the name of one or more polysaccharides that matches each of the following descriptions:
a. the storage form of carbohydrates in animals
b. contains only $尾 (1 鈫� 4)$ -glycosidic bonds
c. contains both $a l p h a (1 鈫� 4)$ - and $a l p h a (1 鈫� 6)$ -glycosidic bonds
d. produces maltose during digestion

Expert verified

Part a) Glycogen is form of a glucose storage type in animals.

Part b) Cellulose contains only $尾 (1 鈫� 4)$ glycosidic bonds.

Part c) $伪 (1 鈫� 4)$ and $伪 (1 鈫� 6)$ glycosidic linkages are found in both amylopectin and glycogen.

Part d) Amylose and amylopectin produce maltose during digestion.

Polysaccharides are carbohydrates that include $10$ or more monosaccharides.
The glycosidic bond is the most important bond in polysaccharide structural stability.
These polysaccharides create more than $10$ monosaccharide units after complete hydrolysis.

Glycogen is form of a glucose storage type in animals.
Glycogen a glucose polymer with a unique structure.
Branches with $a (1 鈫� 6)$ -glycosidic links occur every $10$ to $15$ glucose units, though.
It is a polysaccharide that is more branched than amylopectin.

In plants, cellulose is a primary structural carbohydrate.
The $b e t a (1 鈫� 4)$ -glycosidic bond connects lengthy unbranched glucose units in cellulose.
The enzyme $d$ -amylase hydrolyzes $a l p h a (1 鈫� 4)$ -glycosidic bonds in humans, but not $b e t a (1 鈫� 4)$ -glycosidic bonds.
This is the reason that cellulose could not be digested by humans.

$伪 (1 鈫� 4)$ and $伪 (1 鈫� 6)$ glycosidic linkages are found in both amylopectin and glycogen.
$a l p h a - D$ -glucose units are connected by $a l p h a (1 鈫� 4)$ -glycosidic linkages in amylopectin and glycogen. amylopectin, and every $25$ to $30$ glucose units in glycogen.

Acid hydrolysis or amylase action of amylose and amylopectin produces smaller sugars known as dextrins.
These dextrins are further hydrolyzed by amylase to maltose.
Therefore, amylose and amylopectin produce maltose during digestion.
