  1. Phospholipid
    Glycerol TWO fatty acid and phosphate
  2. Amphipathic Region of Phospholipid
    • Phosphate region- polar, hydrophillic, head
    • Fatty acid chains- nonpolar, hydrophobic, tail
  3. Steroids
    • 4 interconnected rings of C atoms
    • not water soluble
    • cholesterol
    • small change big difference
  4. Proteins
    • structural
    • protective
    • regulatory
    • contractile
    • transport
    • work like enzymes
  5. enzymes bind with protein at
    active site
  6. Protein
    • CHON and some S
    • amino acids


    *remember it has NITROGEN!
  7. amino acids
    • 20 of them
    • common structure with R group
    • side chain determine function
  8. bond between amino acids
    peptide bond!
  9. Protein shape determined by
    intramolecular bonding
  10. primary structure
    amino acids sequence in line
  11. secondary structure
    • B pleated sheets (archordian) 
    • alpha helices (coils)
  12. tertiary structure
    3D shape
  13. quaternary structure
    TWO or more peptides to make larger protein
  14. 5 factors promoting protein folding and stability
    • 1.Hydrogen bonds
    • 2.Ionic bonds and other polar interactions
    • 3.Hydrophobic effects
    • 4.Van der Waals forces
    • 5.Disulfide bridges
  15. shape of protein determines function
    can be denatured and changed by PH and temperature
  16. domain of proteins
    each domain has a function
  17. Nucleic acid
    • info storage and passed down from generation to generation
    • DNA
    • RNA
  18. Nucleotide
    • Monomer
    • phosphate, 5 carbon sugar (ribose or deoxyribose), phosphate group
  19. central dogma
    • DNA to RNA (transcription) 
    • RNA to protein (translation)
  20. Monomer linked to polymer by
    sugar phosphate backbone
