What Does –ose Indicate?

The suffix –ose indicates________________.

What is Glucose?The most common simple

sugar (______________)Used as a source of energy for

living things.

What is Starch?A ______

_______(polysaccharide)Used a source of energy for

living things.

Monosaccharides Glucose Fructose Galactose

Disaccharides Glucose + Glucose =

Glucose + Fructose=

Glucose + Galactose=

Polysaccharides Starch Cellulose Glycogen

How do you test for the presence of simple sugars? To test for the

presence of simple sugars… use Benedict’s Solution.

Add 5 drops of Benedict’s Solution and heat.

If solution changes to orange, then simple sugars are present.

Benedicts

How do you test for the presence of

Starch? To test for the presence of starch… use Lugol’s solution (IKI iodine)

Add 3 drops of Lugol’s solution

If a solutions changes to blue-black, then starch is present.
