Key definitions 4

Question 1

Oligosaccharides

Answer 1

These are molecules with 3 to 10 monosaccharide units.

Question 2

Amylose

Answer 2

Amylose is a complex carbohydrate containing only glucose monomers joined together by 1,4 glycosidic bonds so the molecules form long unchained

Question 3

Amylopectin

Answer 3

Amylopectin is a complex carbohydrate made up of glucose monomers joined together by 1,4 glycosidic bonds and 1,6 glycosidic bonds so the molecules branch repeatedly.

Question 4

Glycogen

Answer 4

This is made up of many a-glucose units joined by 1,4 glycosidic bonds but also has 1,6 glycosidic bonds giving it many side branches.

Question 5

Cellulose

Answer 5

This is a complex carbohydrate with b-glucose monomers and held together by 1,4 glycosidic bonds. It is very important in plant cell walls.
