  1. Biomolecules Book Notes pages 59-63

  2. Biomolecules • All biomolecules contain the element: • carbon

  3. Carbohydrates: • What do they do for our bodies? • Energy, Structure, Cell Identification • Where do we find them in our foods? • Fruit, Vegetables, Pasta, Bread, Soft Drinks • Basic Shape: • C,H,O (1:2:1); Ring Shape • Repeating Molecule: • Monosaccharide (sugar) • Example: Glucose (C6H12O6)

  4. carbohydrates

  5. carbohydrates

  6. Lipids: • What do they do for our bodies? • Storing Energy, Water Movement • Where do we find them in our foods? • Plant Oils, Animal Fats • Basic Shape: • 2 or 3 long chains • Repeating Molecule: • Fatty Acid • Example: Triglyceride (C55H98O6)

  7. Saturated Vs. Unsaturated • Saturated: Animal fat, solid at room temperature, “toothpicks” can cause heart disease • Unsaturated: Plant oils, liquid at room temperature, healthier for you

  8. lipids

  9. Proteins • What do they do for our bodies? • Build, Repair, Cell communication • Where do we find them in our foods? • Lean Meat, Beans, Nuts, Dairy • Basic Shape: • Beaded Necklace • Repeating Molecule: • Amino Acid • Example: Collagen (C5978H9285N1835O1941S31)

  10. protein

  11. Nucleic Acids • What do they do for our bodies? • Contain genetic information (DNA) • Where do we find them? • Biological parents, Every cell has a copy

  12. Review • Use the information you have written above to answer the following questions. • The four major classes of organic compounds are: • Carbohydrates, lipids, proteins and nucleic acids • Fats are lipids that store • Energy • What roles do proteins play in organisms? • Build and Repair
