List of Disaccharides:

Maltose, sucrose, lactose

Pentose sugars:

Ribose, Deoxyribose

Hexose sugars:

Glucose, Fructose, Galactose

Difference between Amylose and Amylopectin (both starches)

Amylose is unbranched, and coiled, and contains only 1-4 glycosidic bonds. Amylopectin is branched and contains both 1-4 and 1-6 bonds.

What is a benefit to a polysaccharide being more branched?

Enzymes can more easily hydrolyse the glycosidic bonds and use for respiration

Benefit of starch being insoluble:

Doesn’t affect water balance

Difference between Alpha and Beta Glucose:

Alpha glucose has the hydroxyl group below whereas Beta has the hydroxyl group above.

Three types of polysaccharides:

Starch ( Amylose and Amylopectin )

Glycogen

Cellulose

Which bonds do Amylopectin and Glycogen contain which Amylose and cellulose do not?

1-6 Glycosidic bonds
