Introduction Carbohydrates consisting a large number of

monosaccharide units

Monosaccharide units linked by Glycosidic bond

High Molecular mass

Taste less

Insoluble in water

Non-reducing in nature

Obtained from Plants and Animals

Starch

Cellulose

Glycogen

All Polymers of Glucose

Starch Found in plants

Plants store food in this form

Rarely found in Animals

Polymer of alpha-D Glucose

Maize, Wheat, Barley are rich sources

Hydrolyzed to form Alpha-Glucose: The energy bank

Cellulose

Cellulose Found in cell wall of Plants

Most abundant carbohydrate

Polymer of Beta-D Glucose

Cotton, Wood etc.

Hydrolyzed to Produce Beta-D Glucose

Hydrolysis not possible in Humans as they lack Cellulase enzyme

Act as Dietary Fiber
