Question 1

what is a monosaccharide?

Answer 1

it is a simple sugar that is made of a number of functional groups. Monosaccharides all have several hydroxyl functional group present and therefore are all highly soluble in water.

Question 2

what are the 3 monosaccharides

Answer 2

Glucose, Fructose, and Galactose

Question 3

where is glucose found?

Answer 3

Question 4

where is fructose found?

Answer 4

Question 5

what are disaccharides?

Answer 5

Disaccharides are two monosaccharides that have bonded through a condensation reaction, with water being produced as a result.

Question 6

what is the change in the structure of the monosaccharides then they undergo a condensation reaction and become a disaccharide?

Answer 6

The only change to the structure of the monosaccharide is at the hydroxyl functional group, which then becomes the glycosidic link.

Question 7

what are the 3 most important disaccharides?

Answer 7

Maltose, Lactose, and Sucrose

Question 8

what 2 monosaccharides combine to create Maltose?

Answer 8

Maltose is formed by the condensation reaction of glucose and glucose
