1. Carbohydrates
Disaccharides
Polysaccharides

2. Important Disaccharides
Maltose = Glucose + Glucose
Lactose = Glucose + Galactose
Sucrose = Glucose + Fructose

3. Maltose 
 -1,4-glycosidic bond
- D-Maltose

4. Lactose
 -1,4-glycosidic bond
α-D-Lactose 

5. Sucrose
α, -1,2-
glycosidic bond

6. Learning Check C4
Identify the monosaccharides in each of the following:
A. lactose
(1) glucose (2) fructose (3) galactose
B. maltose
(1) glucose (2) fructose (3) galactose
C. sucrose

7. Solution C4 A. lactose (1) glucose and (3) galactose B. maltose
(1) glucose and (1) glucose
C. sucrose
(1) glucose and (2) fructose

8. Polysaccharides
Starch
Amylose
Amylopectin
Glycogen
Cellulose

9. Polysaccharides
Polymers of D-Glucose

10. Amylose
