Presentation Transcript

  1. Organic Molecules

  2. Inorganic vs. Organic

  3. Monomers • Simple organic molecules that exists individually or can link with other monomers • Examples: monosaccharide, amino acid, nucleotide

  4. Polymers • Many monomers linked together • Example: carbohydrates, protein, nucleic acid

  5. Anabolic Reaction Catabolic Reaction

  6. Carbohydrate • Monomer = monosaccharide • Elements: C, H, O • H:O=2:1

  7. Disaccharides

  8. Polysaccharide

  9. Functions • Short-term energy storage • Starch and glycogen • Structure • Chitin and cellulose • Cell-to-cell recognition

  10. Nucleic Acids • Monomer = nucleotides • Elements: C, H, P, N, O

  11. Nitrogenous Bases

  12. Examples of Nucleic Acids • DNA (deoxyribonucleic acid) • RNA (ribonucleic acid) • ATP (adenosine triphosphate)

  13. Functions of nucleic acids • Stores and transfers genetic information • Major form of cellular energy

  14. Proteins • Monomer = amino acids • Elements = C, H, O, N, S

  15. 20 different amino acids are required by living things 20 different amino acids

  17. Functions of proteins • Structure • Cellular motility • Muscle contraction • Transport • Immunity (antibodies) • Enzymes • Cellular messages (hormones)

  18. Lipids • Not considered polymers because no 1 repetitive building block • Grouped together because have 1 thing in common • No affinity for water! • Elements: C, H, O, P (sometimes)

  19. Fats

  20. Phospholipid

  21. Steroids

  22. Function • Energy storage (2x as much energy as carbs and proteins) • Structure • Cell membrane • Communication • Steroid hormones
