5 School of Science and Technology, Online Counseling Resource… © 2007, YCMOU. All Rights Reserved.5 Learning Objectives  After studying this module, you should be able to: Describe carbohydrates. Discuss simple & compound sugars. Describe the role of carbohydrate in living systems. Discuss how carbohydrates supplies energy.

6 School of Science and Technology, Online Counseling Resource… Introduction  Carbohydrates are simple organic compounds that are aldehydes or ketones with many hydroxyl groups.  Carbohydrates are the most abundant of the four major classes of biomolecules.  Carbohydrates, corn, and the most common and abundant are sugar come from a wide array of foods - bread, milk, potatoes, fibers, and starches.  They fill numerous roles in living things, such as the storage and transport of energy and structural components.  Additionally, carbohydrates and their derivatives play major roles in the working process of the immune system, fertilization, pathogenesis, blood clotting, and development. © 2007, YCMOU.

7 School of Science and Technology, Online Counseling Resource… Carbohydrates Compounds containing : Carbon Hydrogen Oxygen Defined as : Polyhydroxy derivatives of aldehyde or ketone They are also called as saccharides means sugar. General formula : Cx(H 2 O)y Functional groups : C=O & -OH © 2007, YCMOU. All Rights Reserved.7

8 School of Science and Technology, Online Counseling Resource… Carbohydrates in Body……….  Carbohydrate rich foods, in their natural state are low in calories and high in fiber. Carbohydrates contain about 4 calories per gram.  carbohydrates in our body, are broken down and used as energy source.  When the body doesn't need to use the carbohydrates for energy, it stores them into the liver and muscles.  When carbohydrates are stored in your liver and muscles, it is called glycogen.  When the liver and muscles cells cannot store anymore glycogen, it is turned into fat.  When your body needs a quick boost of energy, it converts glycogen into energy.  When it needs a prolonged burst of energy, it converts fat to energy. © 2007, YCMOU.

9 School of Science and Technology, Online Counseling Resource… Functions of Carbohydrates  Source of energy for living beings.  Storage form of energy, e.g. – glycogen in animal tissue & starch in plants.  Serve as structural components, e.g.- glycosaminoglycans in human, cellulose in plants & chitin in insects.  Constituents of nucleotide that form RNA & DNA, e.g.- ribose & deoxyribose sugar.  Carbohydrates play a role in lubrication, cellular intercommunication & immunity. e.g.- Glycoprotein & glycolipid units of cell surfaces are key participants in cell to cell recognition during development. © 2007, YCMOU.

10 School of Science and Technology, Online Counseling Resource… Classification of Carbohydrates  Classification based on number of sugar units : 1.Simple sugars Monosaccharides : Single sugar unit 2. Compound sugars Oligosaccharides : 2-10 sugar units Polysaccharides : More than 10 sugar units © 2007, YCMOU. All Rights Reserved.10

11 School of Science and Technology, Online Counseling Resource… Simple Carbohydrates © 2007, YCMOU. All Rights Reserved.11 Simple carbohydrates are also known as sugars.

13 School of Science and Technology, Online Counseling Resource… What we learn……….  Carbohydrates are carbon, hydrogen & oxygen containing compounds made up of aldose or ketose sugar.  They are present in all living beings.  Serves vital role in energy storage & transport.  They are divided into monosaccharides, oligosaccharides & polysaccharides.  Monosaccharides are simple sugars while oligosaccharides & polysaccharides are compound sugars. © 2007, YCMOU.
