CARBOHYDRATES

Slide 2

Characteristics of Carbohydrates

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

Slide 8

Important Polysaccharides: Starch

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.

Slide 9

Important Polysaccharides: Cellulose

Important Polysaccharides: Cellulose

Composed of glucose subunits

Different bond formed than starch

Structural component in plants

Cannot be digested by animals

Slide 10

Important Polysaccharides: Chitin

Important Polysaccharides: Chitin

Glucose subunits

Partly derived from non-sugars (nitrogen)

Composes exoskeletons of insects

Note similarity to cellulose.
