1. Warm up What do all these substances have in common?

2. The Mac Daddies of Molecules Or Macromolecules and their functions in living things…..

3. Macromolecules-what are they? They’re giant molecules formed from monomers by polymerization into polymers! They’re giant molecules formed from monomers by polymerization into polymers! Monomers are smaller molecules, like beads in a necklace or links in a chain (think bling). Monomers are smaller molecules, like beads in a necklace or links in a chain (think bling). Polymerization is just a fancy term for becoming a big ole molecule! Polymerization is just a fancy term for becoming a big ole molecule!

4. Macs of Importance for Life Carbohydrates Carbohydrates Lipids Lipids Nucleic Acids Nucleic Acids Proteins Proteins

5. Carbohydrates Made of Carbon:Hydrogen:Oxygen in a 1:2:1 ratio Made of Carbon:Hydrogen:Oxygen in a 1:2:1 ratio Found in fruits, vegetables, & grains Found in fruits, vegetables, & grains Made from monosaccharides (single sugars) which form polysaccharides Made from monosaccharides (single sugars) which form polysaccharides Examples: glucose, fructose, starch, sugars Examples: glucose, fructose, starch, sugars We get energy from carbs! We get energy from carbs!

6. Lipids They will not dissolve in water. They will not dissolve in water. They are made of fatty acids & glycerol They are made of fatty acids & glycerol They are fats,steroids,oils and waxes They are fats,steroids,oils and waxes Examples are margarine, shortening, meats, olive oil, peanut oil Examples are margarine, shortening, meats, olive oil, peanut oil Lipids are used for storing energy (why it pays to have some fat on you!) Lipids are used for storing energy (why it pays to have some fat on you!)

7. Proteins Proteins are just chains of amino acids, like a beaded necklace, that sometimes fold into weird shapes Proteins are just chains of amino acids, like a beaded necklace, that sometimes fold into weird shapes Their functions are VAST!!!!! Their functions are VAST!!!!! –Enzymes (promote chemical reactions) –Provide structure (hair, bones, muscles) –Antibodies (fight infection) –Carry things (oxygen from lungs to rest of body)

8. Nucleic Acids Are made of nucleotides with 3 parts- Are made of nucleotides with 3 parts- –5 carbon sugar+nitrogen base+phosphate group (no that’s not a band) Commonly known as DNA and RNA Commonly known as DNA and RNA What they do: transmit genetic information (in other words, why you have great aunt Edna’s winning smile or uncle Harry’s ears) What they do: transmit genetic information (in other words, why you have great aunt Edna’s winning smile or uncle Harry’s ears)

9. 3-2-1 Name 3 elements that make up the macromolecules. Name 3 elements that make up the macromolecules. 2 functions of proteins 2 functions of proteins 1 reason carbohydrates are important for life 1 reason carbohydrates are important for life
