  25. 25. When studying these biochemical molecules, we are interested in finding out….. <ul><li>what they do for living things. </li></ul><ul><li>what they generally look like. </li></ul><ul><li>what their monomers are. </li></ul><ul><li>and how they may help the body gain energy to sustain life. </li></ul>
  26. 26. YOU CREATE IT: You are about to learn all about the BIG 4. Create an organized way to record the information in your journal. You will learn about: 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 How they help gain energy
  27. 27. LET’S BEGIN WITH CARBOHYDRATES <ul><li>They are the main source for the body to gain energy . They are our fuel! </li></ul><ul><li>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 . </li></ul><ul><li>THINK: CARBS= ENERGY and CELL WALLS </li></ul>WHAT DO THEY DO?
  28. 28. CARBOHYDRATES WHERE ARE THEY FOUND? <ul><li>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) </li></ul><ul><li>--------------------------------------------------- </li></ul><ul><li>In animal products- in MILK </li></ul>
  29. 29. CARBOHYDRATES TYPES THERE ARE 2 TYPES OF CARBOHYDRATES Simple Complex
  30. 30. Simple Sugars are carbohydrates made up of 1 or 2 monomers. They also taste sweet.
  31. 31. Simple Sugars COOKIES and CANDY CAKES FRUITS
  32. 32. Complex Carbohydrates… What are they? Complex Cabohydrates are polymers made up of many monomers. Most also taste starchy.
  33. 33. Complex Carbohydrates FIBER STARCHES VEGETABLES WHOLE GRAINS PASTAS BREADS
  34. 34. CARBOHYDRATES MADE UP OF... Carbohydrates are chains (polymers) made of monomers. The most common monomer of carbohydrates is… GLUCOSE
  35. 35. The shape of Glucose is a hexagonal ring
  36. 36. CARBOHYDRATES AT THE ATOM LEVEL Each carbohydrate is made up of… Carbon, Hydrogen, and Oxygen THINK: “CHO”
  37. 37. Answer the questions in your journal in complete sentences . JOURNAL PAUSE
  38. 38. NOW ONTO PROTEINS <ul><li>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 </li></ul><ul><li>They make up antibodies in the immune system </li></ul><ul><li>They make up enzymes for helping chemical reactions </li></ul><ul><li>They makeup non-steriod hormones which </li></ul><ul><li>THINK: Proteins= membranes, enzymes, antibodies, non-steriod hormones, structural molecules, “MEANS” </li></ul>WHAT DO THEY DO?
  39. 39. MORE ON PROTEINS… The following slides give you a little more in depth info on things that are made of proteins…
  40. 40. Muscles, ligaments, tendons, and bones Without these particular structural proteins, we would look more like this….
  41. 41. Well, maybe not exactly…
  42. 42. Hair, Skin, and Nails
  43. 43. Microscope View of Skin and Nails This is skin This is a nail
  44. 44. 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.
  45. 45. 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. Antibodies
  46. 46. 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! Enzymes
  47. 47. 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 . HORMONES
  48. 48. 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. 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! (The yellow stuff is thyroid hormone)
  49. 49. PROTEINS WHERE ARE THEY FOUND? <ul><li>In plant foods- in the cell membranes </li></ul><ul><li>In animal products- in the cell membranes- in the muscles or living things- cows, chicken, fish… </li></ul>
  50. 50. Proteins
  51. 51. 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)
  52. 52. PROTEINS MADE UP OF... Proteins are made of long chains (polymers) made of monomers. All proteins are made of the monomer… AMINO ACID
  53. 53. The shapes of proteins are like a balled up piece of string Amino Acid chain All wound up
  54. 54. PROTEINS AT THE ATOM LEVEL Each protein is made up of… Carbon, Hydrogen, and Oxygen, Nitrogen and sometimes Sulfur THINK: “CHONS”
  55. 55. Answer the questions in your journal in complete sentences . JOURNAL PAUSE
  56. 56. LIPIDS ARE NEXT <ul><li>They are a great source of STORED ENERGY so we have it in the future. </li></ul><ul><li>They INSULATE the body to maintain normal body temperature and they CUSHION the internal organs for protection. </li></ul><ul><li>They produce hormones for the body called STERIODS </li></ul><ul><li>They waterproof surfaces of animals,plants, and fruits- these are waxes! </li></ul><ul><li>THINK: Waterproof, insulate, steriods, energy, cushion… “WISE C” </li></ul>WHAT DO THEY DO?
  57. 57. LIPIPS…Some interesting info Waterproofing... <ul><li>Fruits produce a waxy coating to keep from drying out. </li></ul><ul><li>The cells in a tulip make a wax which helps coat the leaves. </li></ul><ul><li>Ear wax traps dust, sand, and other foreign particles from going deeper into the ear and causing damage. </li></ul><ul><li>Beeswax- a structural material to hold honey in the hive </li></ul>
  58. 58. LIPIPS…Some interesting info Steriods... There are many different types of steroids. They are all lipids. Their functions vary. Some common steroids are: SEX STEROIDS ANABOLIC STERIODS CHOLESTEROL Like testosterone and estrogen They increase muscle
  59. 59. LIPIPS…Some interesting info Steriods... Some anabolic steroids are illegal And can be dangerous and very unhealthy NATURAL STERIODS IN OUR BODY INCREASE MUSCLE GROWTH AND BONE DEVELOPMENT AND ARE GOOD. THE ILLEGAL ONES THAT ARE SYNTHETIC ARE BAD.
  60. 60. Very Common Effects of Illegal Steroids If used when the person is still growing, they will be shorter as an adult, anabolic steroids will decrease bone growth. Males will experience shrinking of the testicles, and with prolonged use, the steroid will be turned into estrogen in the male body and it will start to lay fatty tissue on the chest, otherwise known as breasts . If genetically predisposed to becoming bald, balding will happen more quickly. If clean needles are not readily available, there is a significantly higher risk of getting AIDS. Future risks of liver cancer & disease. Enlarged heart (one pro athlete’s heart grew to the size of a basketball…obviously he’s dead)
  61. 61. Illegal Steroid Use in Women Some additional effects… Breasts will decrease in size, the opposite of what happens to men. The woman will start to grow facial hair, how quickly depends on her genetic makeup. If she discontinues use, the facial hair will still continue to grow. If she is genetically predisposed to balding, she will start to lose her hair, just as if she was genetically male. Her voice will start to deepen, how quickly depends on her genetics. If she discontinues use, her voice will remain deep.
  62. 62. LIPIDS WHERE ARE THEY FOUND? <ul><li>In plants- in the seeds </li></ul><ul><li>--------------------------------------------------- </li></ul><ul><li>In animals- in adipose tissue, connective tissue, in animals </li></ul><ul><li>--------------------------------------------------- </li></ul><ul><li>Lipids make up the cell membrane of all cells. What’s that double layer called? </li></ul>
  63. 63. LIPIDS MARGARINE OILS BUTTER
  64. 64. LIPIDS MADE UP OF... Lipids are chains (polymers) made of monomers. The most common monomer of lipids is… TRIGLYCERIDES
  65. 65. The Shape of a triglyceride is like the letter E This is a triglyceride molecule
  66. 66. LIPIDS AT THE ATOM LEVEL Each carbohydrate is made up of… Carbon, Hydrogen, and Oxygen THINK: “CHO”
  67. 67. OH NO CHO! Lipids like Carbs? You might have noticed that both carbohydrates and lipids have the elements Carbon, Hydrogen, and Oxygen. “ CHO” A carbohydrate, has twice as many hydrogen atoms as the number of oxygen atoms. EX: C 6 H 12 O 6 (This is a carb= there are double the number of H compared to O) On the other hand, lipids have a lot more than twice the amount hydrogen atoms as the number of oxygen atoms. EX: C 27 H 46 O cholesterol
