1 Monosaccharides and Disaccharides

2 The elements which make up carbohydrates are:
Carbon (C) Hydrogen (H) Oxygen (O)

3 Monosaccharides -Single Sugar- Monosaccharides are: Sweet tasting
Soluble in water Reducing sugars These are the basic building blocks of other carbohydrates of which are the reducing sugars: Glucose Fructose The Formula for glucose is C6 H12 O6

4 Disaccharides -Double Sugars- May be non-reducing Sweet tasting
Water soluble Disaccharides are formed by CONDENSATION REACTION of 2 Monosaccharides, the bond is called a glycosidic bond. Sucrose Maltose

5 Condensation Reactions
The chemical reaction that links monosaccharides together to produce polymers (disaccharides etc) is called a CONDENSATION REACTION. Examples include: 2 glucose molecules to form maltose A glucose and a fructose to form sucrose

6 2 Glucose to form Maltose
+ Hydrolysis Condensation H2O

7 A Glucose and a Fructose to form Sucrose
+ Condensation H2O Hydrolysis

8 Summary So… CLASSIFICATION: The basic sugar unit = the saccharide
1 sugar unit = Monosaccaride 2 sugar units = Disaccharide Examples of Monosaccharides: Glucose, Fructose Examples of Disaccharides: Maltose, Sucrose These are formed by CONDENSATION REACTIONS To reverse the reaction it is called HYDROLYSIS
