1

what is glucose?

a hexose monossacharide that is polar and soluble.

2

where are the hydroxyls on alpha glucose?

both on the bottom of the atom

3

where are the hydroxyls on beta glucose?

one on the bottom one on the top

4

what bonds form between 2 glucose molecules?

glycosidic bonds

5

what type of reaction creates glycosidic bonds?

condensation reaction

6

fructose and glucose make...

sucrose

7

what makes lactose?

galactose and glucose

8

what do 2 alpha glucose make?

maltose

9

what bond is formed between 2 alpha glucose molecules?

1,4 glycosidic bond

10

what is the polysaccharide of glucose called?

starch

11

what are the 2 components of starch?

amylose, amylopectin

12

what is amylose?

glucose molecules with 1,4 glycosidic bonds that form a helix

13

properties of amylose

it is compact and less soluble

14

what is amylopectin?

glucose molecules with 1,4 and 1,6 glycosidic bonds that make it branched

15

properties of amylopectin

has a branched structure making it compact and uses less room for storage

16

what is cellulose made from

beta glucose

17

what is the structure of cellulose?

alternating beta glucose molecules with 1,4 glycosidic bonds. it makes hydrogen bonds with each other forming microfibrils which then join to form microfibrils

18

properties of cellulose

strong, insoluble and are used to make cell walls in plants
