1

What are the 3 monosaccharides?

Glucose
Galactose
Fructose

2

What are the joins involved in disaccharides?

alpha 1-6 glycosidic bonds

3

What molecules make lactose?

galactose + glucose

4

What molecules make sucrose?

fructose + glucose

5

What molecules make maltose?

glucose + glucose

6

What is the consequence of not having lactase?

Lactose remains in gut and pulls water out, diarrhoea

7

What are the 3 main polysaccharides?

Starch
Cellulose
Glycogen

8

What makes starch?

Alpha amylase
Amylopectin

9

What is the difference between alpha amylase and amylopectin

Alpha amylase are glucose molecules linked in straight chains
Amylopectin are glucose molecules that are highly branched
