  • Biological molecules
    • Water
      • reactant
        • cohesive
          • structural support
        • metabolic importance
      • polar
        • good solvent
    • Carbohydrate
      • mono - saccharides
        • simple sugars
          • glucose, galactose, fructose
            • Untitled
      • disaccharides
        • maltose, sucrose, lactose
      • poly - saccharides
        • starch, glycogen, cellulose, chitin
          • iodine test
    • Lipids
      • triglycerides
        • 1 glycerol
          • 3 fatty acids
            • no affect on water potential
              • 2 fatty acids
                • 1 phosphate
      • phospho - lipids
        • 1 glycerol
          • 2 fatty acids
            • 1 phosphate
      • emulstion test
    • DNA + RNA
      • nucleic acids
        • genes non-overlapping
          • replication
            • 1 - DNA helicase break H bonds
            • 2 - free nucleotides form H bonds
            • 3 - DNA polymerase forms phospho -diester bonds
      • A to T G to C
      • polypeptide synthesis
        • Transciption
          • same as DNA replication
            • includes codons
              • mRNA enters cytoplasm at the end
        • Translation
          • mRNA binds to ribsome
            • reaches 'stop' codon
              • polypeptide chain realeased
  • secondary
    • initial folding
    • tertiary
      • further folding
      • quarternary
        • complex
