Example of monosaccharides

Glucose and fructose

19

From animals, is the common substrate for respiration for energy release in cells

Glucose

20

From fruits, sweetens fruits for attraction of animals for seed dispersal

Fructose

21

Can condense to form polymers

Carbohydrate molecule

22

Malt sugar, glucose-glucose and serves as energy source in germinating seeds

Maltose

23

Is glucose-galactose and makes up about five percent of milk

Lactose

24

Table sugar, extracted from sugar cane and it is the sugar found in tea, it is glucose-fructose and serves as the main transport molecules in plants

Sucrose
