1. Biological Molecules SWBAT: Identify structure and function of carbohydrates Standard – 10a

2. Macromolecules  An atom is the simplest form of matter  A molecule is a specific arrangement of atoms grouped together  A macromolecule is a molecule made up of several repeating subunits called monomers  When the monomers are combined you have a polymer  The polymer is the macromolecule

3. Group 1 - Carbohydrates  Carbohydrates is a term that describes a molecule which has one carbon for every water molecule  Carbo = carbon  Hydrate = water  Ratio CH 2 O (1C:2H:1O)  Function  Main energy source

4. Monomer - Monosaccharide  A monomer is a small repeating unit by itself  Monomer of carbohydrate = monosaccharide  Ex. Glucose, Fructose, Galactose, Deoxyribose and Ribose

5. 2 Examples of Carbohydrates

6. Disaccharide  Di means two. In this case 2 monomers bonded together  Disaccharide = 2 monosaccharides bonded together  Ex. Lactose, Sucrose, Maltose  When monomers come together (bond) to form a polymer the process is called polymerization

7. Example of a disaccharide

8. Polymer - Polysaccharide  A polymer is more than 2 monomers bonded together  Polymer = Polysaccharide  Ex. Starch, Cellulose, Glycogen  Starch and Cellulose are found in plants. Humans cannot digest Cellulose  Glycogen is found in Humans  Both Starch and Glycogen are carbohydrates that are used for energy storage

9. Polysaccharide Example  How Many Monosaccharides Make Up This Carbohydrate?

10. Polysaccharide Example  3 chains of linear cellulose polymer chains
