2 CARBOHYDRATES copyright cmassengale

3 Characteristics of Carbohydrates Consist of carbon, hydrogen, & oxygen Energy containing molecules Some provide structure Basic building block is a monosaccharide (CH 2 O) n ; n = 3,5,6 Two monosaccharides form a disaccharide copyright cmassengale

4 Different Forms of Glucose copyright cmassengale

5 Three Monosaccharides C 6 H 12 O 6 copyright cmassengale

6 Dehydration Synthesis of a Disaccharide copyright cmassengale

7 Formation of Disaccharides copyright cmassengale

8 Hydrolysis of a Disaccharide copyright cmassengale

9 Important Polysaccharides: Starch Consists of glucose subunits Plant energy storage molecule Glycogen is a very similar molecule in animals. Starch and glycogen can be digested by animals. copyright cmassengale

10 Important Polysaccharides: Cellulose Composed of glucose subunits Different bond formed than starch Structural component in plants Cannot be digested by animals copyright cmassengale

11 Important Polysaccharides: Chitin Glucose subunits Partly derived from non-sugars (nitrogen) Composes exoskeletons of insects Note similarity to cellulose. copyright cmassengale
