  1. "THE BIG 4" MACROMOLECULES Slides used and modified from: gbn.glenbrook.k12.il.us/academics/science/Staff/cooper/THE%20BIG%204%20JOURNAL%20PACKET.doc

  2. Before you can understand the topics in this unit there are some key vocabulary terms you need to know. Macromolecule Polymer Monomer gbn.glenbrook.k12.il.us/academics/science/Staff/cooper/THE%20BIG%204%20JOURNAL%20PACKET.doc

  3. What is a MACROMOLECULE gbn.glenbrook.k12.il.us/academics/science/Staff/cooper/THE%20BIG%204%20JOURNAL%20PACKET.doc

  4. What do these words mean? Micro MACRO gbn.glenbrook.k12.il.us/academics/science/Staff/cooper/THE%20BIG%204%20JOURNAL%20PACKET.doc

  5. So What Is A Macromolecule? You should be able to define it on your own ! gbn.glenbrook.k12.il.us/academics/science/Staff/cooper/THE%20BIG%204%20JOURNAL%20PACKET.doc

  6. Next Word….. Polymer gbn.glenbrook.k12.il.us/academics/science/Staff/cooper/THE%20BIG%204%20JOURNAL%20PACKET.doc

  7. "Poly" Polygons Polyester Means... gbn.glenbrook.k12.il.us/academics/science/Staff/cooper/THE%20BIG%204%20JOURNAL%20PACKET.doc

  8. MANY POLY means gbn.glenbrook.k12.il.us/academics/science/Staff/cooper/THE%20BIG%204%20JOURNAL%20PACKET.doc

  9. What does “Mono” mean? 1 gbn.glenbrook.k12.il.us/academics/science/Staff/cooper/THE%20BIG%204%20JOURNAL%20PACKET.doc

  10. A Polymer Here are some analogies to better understand what polymers and monomers are…. If the train is the whole polymer, what would be the small groups that make up the train? If the necklace is the polymer, what are the monomers that make up the necklace? gbn.glenbrook.k12.il.us/academics/science/Staff/cooper/THE%20BIG%204%20JOURNAL%20PACKET.doc

  11. A Polymer Here are some analogies to better understand what polymers and monomers are…. If the train is the whole polymer, what would be the small groups that make up the train? If the necklace is the polymer, what are the monomers that make up the necklace?

  12. Now you and a buddy need to think of at least 2 other analogies for a polymer and its monomers. gbn.glenbrook.k12.il.us/academics/science/Staff/cooper/THE%20BIG%204%20JOURNAL%20PACKET.doc

  13. Now we are ready to begin our study of... gbn.glenbrook.k12.il.us/academics/science/Staff/cooper/THE%20BIG%204%20JOURNAL%20PACKET.doc

  14. The Big Four gbn.glenbrook.k12.il.us/academics/science/Staff/cooper/THE%20BIG%204%20JOURNAL%20PACKET.doc

  15. Three out of the 4 types of biochemical macromolecules can be found on food nutrition labels… gbn.glenbrook.k12.il.us/academics/science/Staff/cooper/THE%20BIG%204%20JOURNAL%20PACKET.doc

  16. Look at the label to the left. 3 of the 4 macromolecules can be found in foods. The 3 biochemical molecules found on a nutrition label are: FAT • 1____________________ • 2____________________ • 3____________________ (0 grams in this product) Carbohydrates (13 grams in this product) Protein (9 grams in this product) gbn.glenbrook.k12.il.us/academics/science/Staff/cooper/THE%20BIG%204%20JOURNAL%20PACKET.doc

  17. What is the fourth type of biochemical macromolecule? gbn.glenbrook.k12.il.us/academics/science/Staff/cooper/THE%20BIG%204%20JOURNAL%20PACKET.doc

  18. The 4th type of biochemical macromolecules are the NUCLEIC ACIDS The types of Nucleic Acids • DNA (DeoxyriboNucleicAcid) • RNA (RiboNucleic Acid) gbn.glenbrook.k12.il.us/academics/science/Staff/cooper/THE%20BIG%204%20JOURNAL%20PACKET.doc

  19. DNA “DNA” is short for DeoxyriboNucleic Acid • Now you know why they just call it DNA! gbn.glenbrook.k12.il.us/academics/science/Staff/cooper/THE%20BIG%204%20JOURNAL%20PACKET.doc

  20. When studying these biochemical molecules, we are interested in finding out….. • what they do for living things. • what they generally look like. • what their monomers are. • and how they may help the body gain energy to sustain life. gbn.glenbrook.k12.il.us/academics/science/Staff/cooper/THE%20BIG%204%20JOURNAL%20PACKET.doc

  21. Keep the following in mind when studying this material: Nucleic Acids What they look like Carbohydrates What they do/Where are they Lipids What are they made up of- at the level of atoms Proteins gbn.glenbrook.k12.il.us/academics/science/Staff/cooper/THE%20BIG%204%20JOURNAL%20PACKET.doc

  22. LET’S BEGIN WITH CARBOHYDRATES WHAT DO THEY DO? • They are the main source for the body to gain energy. They are our fuel! • They make up the cell wall in plants which allow them to grow tall, without this carbohydrate, a plant would be a mushy mess! This type of carbohydrate is called Cellulose. THINK: CARBS= ENERGY and CELL WALLS gbn.glenbrook.k12.il.us/academics/science/Staff/cooper/THE%20BIG%204%20JOURNAL%20PACKET.doc

  23. CARBOHYDRATES WHERE ARE THEY FOUND? • In plant foods- in the cell walls of plants --- in fruits, vegetables, peas, beans, SUGAR comes from a plant and so does FLOUR! (pasta, potatoes, bread, candy, cookies) • --------------------------------------------------- • In animal products- in MILK gbn.glenbrook.k12.il.us/academics/science/Staff/cooper/THE%20BIG%204%20JOURNAL%20PACKET.doc

  24. CARBOHYDRATES TYPES THERE ARE 2 TYPES OF CARBOHYDRATES Simple Complex gbn.glenbrook.k12.il.us/academics/science/Staff/cooper/THE%20BIG%204%20JOURNAL%20PACKET.doc

  25. Simple Sugars are carbohydrates made up of 1 or 2 monomers. They also taste sweet. gbn.glenbrook.k12.il.us/academics/science/Staff/cooper/THE%20BIG%204%20JOURNAL%20PACKET.doc

  26. COOKIES and CANDY Simple Sugars CAKES FRUITS gbn.glenbrook.k12.il.us/academics/science/Staff/cooper/THE%20BIG%204%20JOURNAL%20PACKET.doc

  27. Complex Carbohydrates…What are they? Complex Cabohydrates are polymers made up of many monomers. Most also taste starchy.

  28. Complex Carbohydrates WHOLE GRAINS FIBER STARCHES BREADS PASTAS VEGETABLES gbn.glenbrook.k12.il.us/academics/science/Staff/cooper/THE%20BIG%204%20JOURNAL%20PACKET.doc

  29. CARBOHYDRATES MADE UP OF... Carbohydrates are chains (polymers) made of monomers. The most common monomer of carbohydrates is… GLUCOSE gbn.glenbrook.k12.il.us/academics/science/Staff/cooper/THE%20BIG%204%20JOURNAL%20PACKET.doc

  30. The shape of Glucose is a hexagonal ring gbn.glenbrook.k12.il.us/academics/science/Staff/cooper/THE%20BIG%204%20JOURNAL%20PACKET.doc

  31. CARBOHYDRATES AT THE ATOM LEVEL Each carbohydrate is made up of… Carbon, Hydrogen, and Oxygen THINK: “CHO” gbn.glenbrook.k12.il.us/academics/science/Staff/cooper/THE%20BIG%204%20JOURNAL%20PACKET.doc

  32. gbn.glenbrook.k12.il.us/academics/science/Staff/cooper/THE%20BIG%204%20JOURNAL%20PACKET.docgbn.glenbrook.k12.il.us/academics/science/Staff/cooper/THE%20BIG%204%20JOURNAL%20PACKET.doc

  33. NOW ONTO PROTEINS WHAT DO THEY DO? • They are the major structural molecules in living things for growth and repair : muscles, ligaments, tendons, bones, hair, skin, nails…IN FACT ALL CELL MEMBRANES have protein in them • They make up antibodies in the immune system • They make up enzymes for helping chemical reactions • They makeup non-steriod hormones which THINK: Proteins= membranes, enzymes, antibodies, non-steriod hormones, structural molecules, “MEANS”

  34. MORE ON PROTEINS… The following slides give you a little more in depth info on things that are made of proteins…

  35. Muscles, ligaments, tendons, and bones Without these particular structural proteins, we would look more like this….

  36. Well, maybe not exactly…

  37. Hair, Skin, and Nails

  38. Microscope View ofSkin and Nails This is skin This is a nail

  39. Cell Membrane The cell membrane surrounds everything in a cell so it doesn’t leak out. It is kind of like the balloon in a water balloon. The cell membrane is made mostly of protein AND lipids.

  40. Antibodies Antibodies are part of the immune system. When something enters the body that isn’t supposed to be there, like certain bacteria, antibodies find the invader and stick themselves onto it. When a white blood cell finds the invader covered with antibodies, it knows it doesn’t belong there and kills it.

  41. Enzymes Enzymes are proteins that speed up chemical reactions. If you didn’t have enzymes in your stomach to speed up digestion, the food would rot in your stomach because it would take so long!

  42. HORMONES Hormones are chemicals made in glands that are in one place in the body and then put into the blood to be used in another. These are where the hormone producing glands are located in your body.

  43. The thyroid is found in the middle of your neck, by your voice box. Here is a picture of those cells secreting the thyroid hormone. (The yellow stuff is thyroid hormone) Thyroid hormone regulates how fast your body uses energy. If you have an over active thyroid, you use energy quickly and tend to be very thin and have a hard time putting on weight. If you have an under active thyroid gland, you use energy very slowly and tend to carry more body fat and have a difficult time losing it. Don’t be quick to think you have a thyroid problem if you are overweight, chances are it’s actually your eating and exercise habits!

  44. PROTEINS WHERE ARE THEY FOUND? • In plant foods- in the cell membranes • In animal products- in the cell membranes- in the muscles or living things- cows, chicken, fish…

  45. Proteins

  46. Proteins Aside from the protein found in animal sources…protein can also be found in fruits, vegetables, grains, and nuts. (it just does not have as many amino acids)

  47. PROTEINS MADE UP OF... Proteins are made of long chains (polymers) made of monomers. All proteins are made of the monomer… AMINO ACID
