Carbohydrates
 Functions
 Supply energy to cells.
 Store energy.
 Make cell and organism parts.
Types of carbohydrates
 Single Sugar
 Glucose C6H12O6
Types of carbohydrates
 Double Sugar, table sugar
 Succrose, storing energy
Dehydration Synthesis
 How 2 sugars join together, condensation reaction,
remove water H, OH from the 2 sugars.
Types of carbohydrates
 Polysaccharides [many sugars]
 Starch made by plants, storing energy
Types of carbohydrates
 Glycogen, made by animals.
 Digests to glucose faster than starch.
Glycogen
Structural Carbohydrates
 Cellulose, wood [isn’t digested]
Structural Carbohydrates
 Chitin, exoskeletons [insects, crustaceans]
