Characteristics of Carbohydrates Consist of carbon, hydrogen, & oxygen Energy containing molecules Some provide structure Basic building block is a monosaccharide (CH2O)n ; n = 3,5,6 Two monosaccharides form a disaccharide copyright cmassengale

Different Forms of Glucose copyright cmassengale

Three Monosaccharides C6H12O6 copyright cmassengale

Dehydration Synthesis of a Disaccharide copyright cmassengale

Formation of Disaccharides copyright cmassengale

Hydrolysis of a Disaccharide copyright cmassengale

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

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